如何从控制台安装LEPTONICA版本？

Question

我在CentOs 8上以这种形式安装了http://www.leptonica.org/source/leptonica-1.80.0.tar.gz：

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

最后，我得到以下输出：

  ...
  ...
  ...

    CCLD     wordsinorder
    CC       writemtiff.o
    CCLD     writemtiff

  ----------------------------------------------------------------------
  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.

然而，我希望检查/确认版本LEPTONICA安装在此服务器和其他服务器，许多搜索在谷歌，但我只找到这个命令：

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

但这只显示“是，LEPTONICA已安装！”

请告诉我如何从控制台获取LEPTONICA版本？

如何全局添加/put路径到leptopnica以安装任何其他需要LEPTONICA的软件？

谢谢

Answer 1

使用pkg-config工具: pkg-config --modversion lept

或者创建这个简单的程序(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;
}

可以很容易地使用以下命令进行编译：

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