Using My Libraries in Linux 1

AbidingDude · Nov 26, 2019

I started bringing all of my C libraries and projects to my Linux drive. Currently I'm using Windows and the ancient Borland C 5.5 compiler. (I know. It's old, but I know it really well and it's free.)
To configure the Borland compiler to automatically look in my homemade libraries directory, I have a line in the BCC32.cfg file (where "mylibs" are my routines):

-I"C:\BC55\INCLUDE";"C:\BC55\MYLIBS"

I'm getting used to Linux (Mint), and I just started learning gcc. I just learned about the "ar" command to add my object files to a static library, but how do I get gcc to automatically check my homemade libs folder? Is there a config file for gcc? If there is I couldn't find it.

https://gcc.gnu.org/onlinedocs/gcc/Environment-Variables.html

In your .profile/.bashrc or similar
[tt]export LIBRARY_PATH=/path/to/my/lib
export CPATH=/path/to/my/headers[/tt]

Thanks. I tried that. I copied and pasted those two lines to the end of my '.profile' file:

[tt]export LIBRARY_PATH=~/Cthings/mylibs
export CPATH=~/Cthings/mylibs[/tt]

but I'm still getting "No such file or directory" errors. What am I missing?

Try using say [pre]$HOME[/pre] rather than [pre]~[/pre]

Or failing that, absolute paths.

Not everything understands ~ shell magic.

Thank you. That worked. But after I made the change to the '.profile' file, I had to reboot for it to take effect. Is there a way to reload that file without having to do that?

Your .profile comes into effect when you login.

So all you need to do is logout and login again.

Also, you can re-read it by just typing in
[tt]. $HOME/.profile[/tt]
