无法使用ta-lib编译源

Question

I'm trying to use the ta-lib ( http://ta-lib.org/ ) C API in my C application. I downloaded the sources of ta-lib, installed them on my system using make install. Library compiled successfully and I have its binaries in /usr/local/lib/ . Then I compile my app as suggested on ta-lib site:

$ gcc -L/usr/local/lib -lta-lib -o tlc talib_test.c
/usr/bin/ld: cannot find -lta-lib
collect2: ld returned 1 exit status
$

Any ideas what's going wrong?

OS: I'm using Ubuntu 9.

Answer 1

Is there any chance that you have installed a 32-bit copy of libta-lib.so and are compiling a 64-bit test program, or vice versa? That is, could you have a mismatch in the type of library?

Failing that, have you looked at /usr/local/lib to check that you have libta-lib.so in there? Or could it be that the library is actually called libta.so or something like that, so you need to specify -lta on the command line?

On my Mac, the library was installed as shown (after a couple of minutes compilation):

/usr/bin/install -c .libs/libta_lib.lai /usr/gnu64/lib/libta_lib.la
/usr/bin/install -c .libs/libta_lib.a /usr/gnu64/lib/libta_lib.a

This would require -lta_lib with an underscore instead of -lta-lib with a dash.

Answer 2

Where is libta-lib.a ? The error message suggests the linker cant find the library.
