Multiple working directory about cl-cxx-jit HOT 10 CLOSED

Hi,

• Append -I/your/path to *cxx-compiler-flags* --be careful about spaces-- .
• Then Append -l... to *cxx-compiler-link-libs* --may use -L for files spread across the system--.

*cxx-compiler-flags* defaults to -std=c++17 -Wall -Wextra -I/usr/include/eigen3. see Flags Table for details.

Kindly feel free to ask for improvements.

from cl-cxx-jit.

Another issue is that, no matter how I update the ld linker for the system and cxx-compiler-link-libs and cxx-compiler-flags, it seems cxx-jit cannot find the corresponding libraries with -lmylib flag, I was wondering if this is the problem on my side or the problem with cxx-jit itself, would you mind helping me with this? Your help is greatly appreciated!

The error message would help,so kindly post it.

Assuming your lib is named libmylib.so, you have to add -L/path/to/dir as well as -lmylib. See -l and -L compiler flags for more info.

Or add your lib full path /path/to/libmylib.so as a flag.

from cl-cxx-jit.

That is exactly what I did, I added -L/path/to/mylib, and -lmylib, and update ld, then sudo ldconfig and also add /path/to/libmylib.so, so I had this question.

The error message would be:
/tmp/plugin.cpp:1:10: fatal error: mylib/foo.h: no such file or directory

Sorry to bother again, did you have the chance to check this issue yet

from cl-cxx-jit.

/tmp/plugin.cpp:1:10: fatal error: mylib/foo.h: no such file or directory is an error for header file inclusion. -I

let the header file full path is /home/me/code/mylib/foo.h, you have to add -I/home/me/code to *cxx-compiler-flags*, so compiler would find #include "mylib/foo.h".

That is exactly what I did, but the problem persist. Would you mind checking on your side, for a project installed using cmake, to be imported using cxx-jit

from cl-cxx-jit.

I need some context to reproduce, so kindly provide a complete command like the following:

CL-USER> (cxx-jit:from '("asd.h") 'import nil )

"/usr/bin/g++ -shared -fPIC -Wl,--no-undefined -Wl,--no-allow-shlib-undefined -std=c++17 -Wall -Wextra -I/usr/include/eigen3 /tmp/plugin.cpp -o /tmp/plugin.so -lm" 
"/tmp/plugin.cpp:1:10: fatal error: asd.h: No such file or directory" 
"    1 | #include \"asd.h\"" 
"      |          ^~~~~~~" 
"compilation terminated." 
NIL
CL-USER> 

Plus your project directory tree. minimal complete example would also help.

I have no issue using the lib.

Do you mind if we discuss through email

Nope.
