But included in the above issue are the build tools themselves. For instance, some of the GNU build automation tools packaged in Solaris 11.3 are already rather outdated, among them: autoconf which requires M4 and automake which requires autoconf. To successfully build many other software it's highly recommended to build and install more up-to-date versions of this build automation tools themselves. I'd suggest doing so at least for the following GNU build automation tools (➝ means "depends on", thus begin refreshing this tools in the reverse order show below):
- automake ➝ autoconf ➝ M4 ⇢ libtool ⇢ libsigsegv
For instance: Solaris 11.3 packages automake-19 (v1.9.6), automake-110 (v.1.10) and automake-111 (v.1.11.2), but neither of these are good enough for building more recent third-party software versions. Other software, such as Firefox, requires (?) autoconf version 2.13, but Solaris 11.3 furnishes only version 2.68.
According to the more traditional conventions adopted by Solaris, these extra software are supposed to be located under /opt which indeed is the safest location instead of /usr/sfw or /usr/gnu because we don't want to mess with the built-in strategies of Solaris itself already trying to cope with GNU somehow. Hence, the best practice for manual additions is to focus on pointing to /opt which includes specifying --prefix=/opt/... to the GNU build automation tools (typically the configure script) or something equivalent to any other build automation tool.
NOTE
NOTEIt's also required to install IPS packages for the GNU Compiler Collection (developer/gcc) and many other GNU tools (pkg search -o pkg.shortfmri '*:set:pkg.fmri:*gnu*'), even if you (plan to) have Developer Studio (developer/developerstudo-125) installed as well.
NOTEThe GCC version supplied with Solaris 11.3 only covers the full standards of C89 and C++03. All other standards have only partial support, hence to get more solid results always make these explicit, typically through the environment variables CFLAGS="-std=c89" and CXXFLAGS="-std=c++03" or their equivalent. But you should prefer using the respective GNU extensions to these flags, gnu89 and gnu++03, unless you're really, really, after a strict portability at the expense of sacrificing any platform specific quality and optimization goodies. With the build automation tools the general approach is to adjust to platform specifics on the bases of specific defines (-D at command-line and #ifdef / #ifndef at the source code).
If true full C++11 support is required, you'll have to attempt building a more recent version of GCC. Not even Developer Studio truly fully supports C++11 as it relies on GCC under the hood by typically linking in libgcc_s.so.1. One proof of this limitation is that locales aren't fully supported.
Since Solaris 11.4 Beta the GCC version has bumped to 5.5.0 theoretically supporting the full standards of C11 and C++11. But some C++11 features seem still missing such as the previously mentioned locales issue. Hence, to some extent, you may benefit from setting the environment variables CFLAGS="-std=c11" and CXXFLAGS="-std=c++11" or their equivalent. But again may prefer to use the respective GNU extensions to these flags, gnu11 and gnu++11.
The general work-flow for installing from the GNU build automation tools is:
- Get the tarball (typically a .tar.bz2 or .tar.xz)
- Set up a dedicated and delegated ZFS infrastructure
- Extract the tarball and take an initial snapshot (@source)
- Clone the @source to a build-target specific dataset
- Take a snapshot (@start) from the recent clone.
- Set up the temporary environment variables for the build-target
- Configure the automated build and take a snapshot (@config)
(in case of errors, instead of a snapshot, do a rollback to @start) - Perform the build and take a snapshot (@build)
(in case of errors, instead of a snapshot, do a rollback to @config) - Pre-create the /opt/... destination as a VARSHARE ZFS dataset
(take a snapshot @release of the /opt/.../build-target) - Perform the installation (as root) and take a snapshot of /opt/...
- Optionally, create a package or a compressed tarball from the results
- Set up the necessary permanent environment variables
As for the directory name under /opt a suggestion is:
name-version/build-targetFor instance:
sqlite-3.19.3/gnu64This way it's possible to gather under a main directory (basename) multiple build-targets to select from, such as: gnu32, gnu64, sun32, sun64 and so on...
NOTE
In case of third-party software to be located under /opt, the choice of rpool/VARSHARE as the root to the underlying ZFS dataset is just a simplification. The rpool/VARSHARE suites well for certain system software that shouldn't be impacted by boot environment issues. The best idea for third-party software would be to have another dedicated ZFS pool, much in the same way as it as good idea to have another dedicated ZFS pool for rooting /export instead of the default rpool/export.
Now let me show a full example where I build a 64-bits M4:
$ DS=rpool/export/home/.../software$ zfs create -p $DS/M4/m4-1.4.18
$ cd ~/software/M4
$ gtar xf /tmp/m4-1.4.18.tar.xz
$ M4=$DS/M4/m4-1.4.18
$ zfs set readonly=on $M4
$ zfs snapshot $M4@source
$ zfs clone $M4@source $M4-gnu64
$ zfs snapshot $M4-gnu64@start
$ zfs get -o property,value readonly,compressratio,dedup $M4

compressratio 1.99x

$ zfs list -r -t all -o name $DS/M4

Now I set up the temporary environment variables for the build-target. Note that I gather what's necessary on a non-executable file, setenv-build-target, and then just "source" it to integrate the values in the current session (in my particuar case I just opted to specify one more flag for the minimum architecture of core2 but this is not important for this post):
$ cat setenv-gnu64
export CONFIG_SHELL=/bin/bash
export CC=/usr/bin/gcc
export CFLAGS="-m64 -march=core2 -std=gnu89"
export CXX=/usr/bin/g++
export CXXFLAGS="-m64 -march=core2 -std=gnu++03"
PKG=/usr/gnu
if [[ -d "$PKG" ]] ;
then
CFG=$PKG/bin
! [[ "$PATH" =~ "$PKG" ]] && \
export PATH=$CFG:$PATH
fi
$ source setenv-gnu64
But wait! While reading through the above README and INSTALL files, I've found that M4 has an optional dependency that would be very interesting to pre-install: libsigsegv. At the time of this writing the current version is 2.11, Solaris 11.3 offers version 2.6, but M4 version 1.4.18 recommends a version no less than 2.9. To address this issue, I temporarily stop the M4 building work-flow and then I set to repeat all the steps above but this time for libsigsegv (by the way, naturally the target-build must match!). But before returning to M4 I need to complete the building steps of libsigsegv as follows:

Good luck.
AFAIAC (as far as I am concerned) the configuration result is reasonably acceptable and no message got me worried, so I go on as planned (and always use gmake, not make because Solaris' make although very good isn't the one expected which is if fact GNU make know in Solaris as gmake).

NOTE
Non-Solaris people, which isn't used to roles may prefer the convenience of using sudo instead of "su -", but I don't. Furthermore, in this context, sudo doesn't offer any advantage and may even get in the way unless virtually unrestricted in which case it could be even more dangerous and error-prone.
Now I can resume the build automation for M4:
$ cd ~/software/M4/m4-1.4.18-gnu64
$ ./configure \
--prefix=/opt/m4-1.4.18/gnu64 \
--with-libsigsegv-prefix=/opt/libsigsegv-2.11/gnu64 \
--with-syscmd-shell=/bin/bash
NOTE
If setenv-gnu64 didn't setup /usr/gnu/bin a pitfall would be revealed regarding grep. And that's and example why we should always review messages and logs:
checking whether C symbols are prefixed with underscore at the linker level...
grep: illegal option -- E
Usage: grep [-c|-l|-q] -bhinsvw pattern file . . .
This would require me to start over the "configure" step:
$ zfs rollback $DS/M4/m4-1.4.18-gnu64@start
The problem is that the configure script does non-trivial usage of grep and expects a GNU grep, not a Solaris grep. In Solaris, GNU grep called ggrep or the /usr/gnu/bin should come before /usr/bin in PATH. Sometimes, resolving this issue may not be an easy task because it may be difficult to evaluate the impacts of a chosen approach, tough it should be quite reasonable to put /usr/gnu/bin ahead in PATH as we are using GNU tools anyway... I would suggest try what's reasonable and observe and take action as needed and as possible. Nevertheless, comparing the output of both approaches one can be surprised:
## When /usr/gnu/bin comes ahead in PATH
21 checking for grep that handles long lines and -e... /usr/gnu/bin/grep
22 checking for egrep... /usr/gnu/bin/grep -E
## Otherwise, the usual Solaris without GNU paths
21 checking for grep that handles long lines and -e... /usr/bin/ggrep
22 checking for egrep... /usr/bin/ggrep -E
In both cases the detection is correct and adjusted accordingly. The problem is that throughout the ordinary code in the configure script, the correct detection is not being taken into account, that is, it's hard-coding grep when it shouldn't! That's a bug due to taking for granted that a GNU grep is always available and is exactly spelled 'grep'!
