Subject Re: Compiling mod-jk plugin for SunOne on Solaris

Option 1) (Quick and dirty): Deploy It's *not* the
compiler. The lib contains some machine specific runtime routines, for
which appropriate machine statements are not available.

Option 2): Compiling statically. If you've got good control over the
compilation process you can add "-static-libgcc" to gcc as flags. If you
don't want to find out, where all the gcc compile flags are coming from
(configure, environment variables etc.) you can decide to make all
compiles using static libgcc by hacking a specs file.

a) dump a specs file by calling "gcc -dumpspecs".

b) Edit the results and throw everything away except the block
beginneing with "*libgcc". The exact structure depends on the gcc
version. Here is an example:

-lgcc_eh}%{shared-libgcc:-lgcc_s -lgcc}}%{shared:-lgcc_s}}}

Caution: this is only two lines, the second one is pretty long.

Now edit to make gcc link against libgcc (this is the static version)
instead of libgcc_s (the shared one) even if it has been called to
produce a shared object. In our example the result would be:

-lgcc_eh}%{shared-libgcc:-lgcc -lgcc_eh}}%{shared:-lgcc -lgcc_eh}}}

Save this file, e.g. as /my/gcc.specs.

Then set the environment variable CC to "gcc -specs=/my/gcc.specs" and
start building. You can check the library dependencies of the resulting
"*.so" file by using "ldd".

Good luck.
