Hi,
I intend to compile octave-2.1.44 on a celeron 600MHz running slackware
8.0 (kernel 2.2.xx, gcc 2.95). Most of the tools required by the package
are compatible with my system, but it requires a newer version
of the readline library (updated, without unpleasant
side-effects) and gcc-3.2.2.
I do not plan to replace the present compiler, as that might interfere
with some of the other programs, but rather use hte new version for
specific tasks.
I need pointers to how to do it (preferably answering also the why
questions).
Specifically:
I downloaded, compiled and installed the compiler (with
prefix=/usr/local/gcc-2.3.3). I see there some executables (cpp, gcc, g++,
g77, which I know I will need, but also things like gcj, gcjh, gcov etc,
which I don't know what's their purpose), some include files and some
libraries.
I guess the first thing to do is to inform the linker about these
libraries. As they are in a non-standard location, I have to tell
somehow ldconfig where to look for them. I don't expect it to look with a
flashlight in all the dark corners of my system, for new libraries.
Next, I have to tell the make process to use these tools. Are there any
option arguments that can be given to make to this purpose, or I have to
temporarily change the soft links of gcc & comp. ?
In the end, will octave know to link to the proper run-time libraries ?
Here I am completely in the dark.
Any answer or pointer to answers will be most welcome.
Thanks a lot, Avraham
