Using libxlsxwriter : how to use -lz

<< < (3/4) > >>

Miguel Gimenez:
msys should use the same toolchain of step 1, you can use gcc --version to check which version msys and cmd are using. Try msys-1.0 from this link:

http://downloads.sourceforge.net/mingw/MSYS-1.0.11.exe

bonelli:
Msys 1 installed, binded to C:/MinGW using etc/fstab

gcc -- version returns 9.2.0, using cmd or msys

Note:
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin
is
C:\MinGW\mingw32\bin
I don't know why it didn't use the ld.exe in C:\MinGW\bin
Sounds like they like spaghetti.

Miguel Gimenez:
Try copying libz.a into "/d/soft/lib/xlsx/src" and run make again. My MinGW installation (MinGW-w64) has a built-in libz.a, so this step is not needed.

bonelli:
I already did that, but the lib is still not found. Any way to specify where the lib is using the command line?

bonelli:

--- Code: ---make LDFLAGS="-L."
--- End code ---
  did the job.  :)

How do you do to take care of the global variables? I didn't see where in your project you are asking to use global variables.
