how to get VERSION installed of LEPTONICA from console?

Question

I'm at CentOs 8 and I installed http://www.leptonica.org/source/leptonica-1.80.0.tar.gz in this form:

wget http://www.leptonica.org/source/leptonica-1.80.0.tar.gz
tar xzvf leptonica-1.80.0.tar.gz
cd leptonica-1.80.0
./configure
make && make install

finally I get this output:

  ...
  ...
  ...
    CC       wordsinorder.o
    CCLD     wordsinorder
    CC       writemtiff.o
    CCLD     writemtiff
    CC       yuvtest.o
    CCLD     yuvtest

  ----------------------------------------------------------------------
  Libraries have been installed in:
     /usr/local/lib

  If you ever happen to want to link against installed libraries
  in a given directory, LIBDIR, you must either use libtool, and
  specify the full pathname of the library, or use the '-LLIBDIR'
  flag during linking and do at least one of the following:
     - add LIBDIR to the 'LD_LIBRARY_PATH' environment variable
       during execution
     - add LIBDIR to the 'LD_RUN_PATH' environment variable
       during linking
     - use the '-Wl,-rpath -Wl,LIBDIR' linker flag
     - have your system administrator add LIBDIR to '/etc/ld.so.conf'

  See any operating system documentation about shared libraries for
  more information, such as the ld(1) and ld.so(8) manual pages.

  [root@guest ~]#

however I want CHECK/CONFIRM version LEPTONICA installed in this server and OTHERS servers, many searchs in GOOGLE, but I only find this command:

[root@guest /]# ldconfig -p | grep -i lept
        liblept.so.5 (libc6,x86-64) => /lib64/liblept.so.5
[root@guest /]#

but this only show "yes, LEPTONICA is installed!"

please, some idea about how I can get LEPTONICA VERSION from console?

how add/put PATH to leptopnica globally to install any other software requiring LEPTONICA ?

thanks

Answer 1

Use pkg-config tool: pkg-config --modversion lept

Or create this simple program (leptonica_version.c):

#include <leptonica/allheaders.h>

int main() {
  char *versionStrP;
  versionStrP = getLeptonicaVersion();
  printf("%s\n", versionStrP);
  lept_free(versionStrP);
  
  versionStrP = getImagelibVersions();
  printf("  %s\n", versionStrP);
  lept_free(versionStrP);
  return 0;
}

that could be easily compiled with:

gcc leptonica_version.c -o leptonica_version -I/usr/local/include -L/usr/local/lib -llept
