libaltm.a -- libm.so Replacement for OpenServer 5.04
 

Here it is... libaltm.a is a regular ar library containing -fPIC (Position Independent Code) versions of libm.a source files. It was compiled with gcc 2.95.2 for SCO OpenServer 5.04. I needed this to get Python 2.1.2 to build, and when I went looking I found many other poor suckers in the same boat.

I built a libm.so file the same way I have successfully built shared libs on Linux systems, but it just doesn't work. So then I got this harebrained idea, and it does work.

This was taken from glibc-1.09.tar.gz off my old Linux Secrets CD. I coerced it into building as a static library, then in the math subdirectory I changed the Makefile to add:

CFLAGS += -fPIC

Then I did

make clean
make
ar cruv libaltm.a *.o
ranlib libaltm.a

I tried to build a libm.so like this:

gcc -shared -o libm.so *.o

but when I link against it I get errors running the resulting binaries.

 


Installation:

You need to put libaltm.a in the /usr/local/lib folder. Change -lm to -laltm in the CFLAGS or on the gcc command line to get programs to link with it.

So far it seems to work...
