Building on FreeBSD

From Gnash Project Wiki

As of mid Feb, 2008, Gnash builds out of the box on FreeBSD 6.3, using g++ 3.3.5. Here's the data on my system's configuration. This is a completely up to date OpenBSD installation, so if you have any problems, some of your packages may be out of date, or missing.

$ uname -a
FreeBSD 6.3-RELEASE FreeBSD 6.3-RELEASE #0: Wed Jan 16 04:45:45 UTC 2008  i386
$ head -1 /etc/motd
FreeBSD 6.3-RELEASE (SMP) #0: Wed Jan 16 04:45:45 UTC 2008

While Gnash does build with the older GCC used by default on FreeBSD, the newer 4.2.x version also builds Gnash just fine. The older GCC has problems with optimizing however, and several files can't be compiled at -O2. Several builds of GCC 4.2.x are available, and work better at the higher optimization levels.

$ g++ -v 
Using built-in specs.
Configured with: FreeBSD/i386 system compiler
Thread model: posix
gcc version 3.4.6 [FreeBSD] 20060305

Q: With FreeBSD 6.1-RELEASE I run ./ and get:

processing ./libltdl
Running libtoolize --force --copy ...
You should update your `aclocal.m4' by running aclocal.
You should update your `aclocal.m4' by running aclocal.
Running aclocal ...
aclocal: cannot open > aclocal.m4: Permission denied
Running autoheader...
Running automake --add-missing --copy ...
Running autoconf ...
autom4te: cannot open configure: Permission denied

Though "configure" is created

A: The error messages appear to originate in libltdl/ (which has its own and aclocal.m4).

The libtool installation on FreeBSD has the libltdl files (which are copied by libtool --ltdl when called by readonly (u-w) in $installpath/share/libtool/ltdl. When the permissions are set to u+rw, the error messages go away.

Suggested workaround from Germain Le Chapelain (user germ on sourceforge):
