Using My Libraries in Linux

Using My Libraries in Linux

Using My Libraries in Linux

(OP)
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.

RE: Using My Libraries in Linux

https://gcc.gnu.org/onlinedocs/gcc/Environment-Var...

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

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

export LIBRARY_PATH=~/Cthings/mylibs
export CPATH=~/Cthings/mylibs

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

RE: Using My Libraries in Linux

Try using say 
$HOME
rather than 
~

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?

RE: Using My Libraries in Linux

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
. $HOME/.profile
