This howto explains the steps to get lazarus svn and fpc svn up and running starting from a clean Solaris 10 system (adapt to your processor, I'm on x86). It assumes that you have already used svn and build fpc and lazarus from source before.

Install the FPC Compiler Binaries

Get and install fpc 2.4.4 from and the install script for x86.

For Solaris SPARC the most recent version is 2.4.2. It can be downloaded from, the install script from

Install Required Libraries

Install following packages from These are the versions at the time of writing (7/2011). This is a long list because gnu binutils, make, subversion (with a lot of dependencies) and gtk2 are pulled in:

apache-2.2.19 atk-1.18.0 binutils-2.21.1 cairo-1.4.10 coreutils-8.11 expat-2.0.1 fontconfig-2.8.0 freetype-2.4.2 gcc-3.4.6 gdb-6.8 glib-2.25.13 gtk+-2.12.0 jpeg-8a libiconv-1.13.1 libintl-3.4.0 make-3.82 ncurses-5.7 neon-0.29.5 openldap-2.4.24 openssl-1.0.0d pango-1.18.2 render-0.8-sol10-intel-local renderproto-0.9.3 sasl-2.1.21 subversion-1.6.12 tiff-3.9.4 xft-2.1.2-sol10-intel-local xrender-0.8.3-sol10-intel-local zlib-1.2.5

These versions are all available for SPARC.

Adapt your PATH variable to get the gnu version of the binutils:

$ export PATH=/usr/local/bin:$PATH

$ export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

Check your GTK2 installation:

$ gtk-demo

Get and Build Sources

$ svn co fpc

$ cd fpc

$ make clean all

$ su

# make install INSTALL_PREFIX=/usr

/etc/fpc.cfg installed with 2.4.4 is fine for your new 2.5.1 installation.

$ svn co lazarus

$ cd lazarus

$ make clean all OPT="-k-lumem" FPC=/usr/lib/fpc/2.5.1/ppc386

There is a compatibility problem with the solaris libc and glib2 from Lazarus crashes in many cases with a "Glib-Error (recursed) ** :gmem.c:140: failed to allocate 42 bytes". The solution is to use libumem which is the "better" memory manager for Solaris and shipped standard since Solaris 9 update 3. Running lazarus with " ./lazarus" solves the problem. An easier solution is to link statically libumem with the make option OPT="-k-lumem". The loader will load libumem automatically before libc. Note that the parameter -k-lumem needs to be added to every lazarus project that uses the LCL in Project/Project Options/Compiler Options/Other. Adding {$linklib umem} to the program before any reference to libc has the same affect.

Solaris 11 Express


Depending on the installation media, gnome is already installed or can easily be installed by installing the slim_install package. subversion and gnu-binutils can be installed from the solaris repository with "pkg install" or the graphical Package Manager.

Gnu-binutils version 2.19 has a bug in the linker ld: the internal linker script is corrupt. Best solution is to build binutils from source. First you'll need to install the packages gcc-3 and header-math (math.h not installed by default).

$ wget

$ $ tar xf binutils-2.21.1.tar.bz2

$ cd binutils-2.21.1

$ ./configure --prefix=/usr/local/binutils-2.21.1

$ make

$ su

# make install

# rm /usr/bin/gld

# ln -s /usr/local/binutils-2.21.1/bin/ld /usr/bin/gld


The crash in glib still exists in Solaris 11. The -k-lumem solution is still needed.
