Subject RE: [NOT SOLVED]Tomcat native library Not found in Solaris 9
Date Wed, 01 Aug 2007 22:30:05 GMT

Please give me some tips for compiling libtcnative on Solaris 9 without
the dynamic dependence on
libgcc_s.1.so.  We ship tomcat with our product.  On customer
installations, we cannot assume
that libgcc_s will be found in some standard location.

I have searched a lot on the web. I am also trying to compile gcc with
--disable-shared option.
I am running into some issues while trying to compile gcc. 
1) How to modify Tomcat native's configure script to link libgcc
statically?
2) What are the prerequisites before doing step 1)?

We are using Tomcat 5.5.23. I am using tcnative-1.1.8-src with
OpenSSL-0.9.8b.

--Thanks
Lakshmi

It's very likely, that it depends on the same lib in RedHat. You can
check by using "ldd libtcnative-1.so".

The difference is: gcc is a fundamental part of the OS with Linux, so
libgcc_s.so is ususally installed in a standard library location for
Linux. Under Solaris it's an optional add-on installed in a separate
place.

Personally I always find it anoying, that gcc put's a dependency on its
own runtime lib into the compiled code. You could prevent it doing so,
by changing its specs file (tehreby compiling in its convenience
routines statically).

Rainer
