• Running Red Hat 7.1 (glibc 2.2.2) but compiling for Red Hat 6.2 compatability.
  See RELEASE-NOTES
  

          export LD_ASSUME_KERNEL=2.2.5
          . /usr/i386-glibc21-linux/bin/i386-glibc21-linux-env.sh
      

• To add libraries to be included during dynamic linking, add the entry to the file /etc/ld.so.conf OR add the the library path to the environment variable LD_RUN_PATH.

  Sample: /etc/ld.so.conf

  /usr/X11R6/lib /usr/lib ... .. /usr/lib/sane /usr/lib/mysql /opt/lib

  Add the library path to this file and then execute the command ldconfig to configure the linker run-time bindings.
  You can use the "-f file-name" flag to reference another configuration file if you are developing for different environments. See man page for command ldconfig.

• To include the library during execution, add the library path to the environment variable LD_LIBRARY_PATH.
  (Linux/Solaris: LD_LIBRARY_PATH, SGI: LD_LIBRARYN32_PATH, AIX: LIBPATH, Mac OS X: DYLD_LIBRARY_PATH, HP-UX: SHLIB_PATH)

• Direct loader to preload a specific shared library before all others: export LD_PRELOAD=/usr/lib/libXXX.so.x; exec program
  Also see:
  • man page to: programming interface to the dynamic linking loader.
  • Linux function interception.

• Including a library in the compile statement: gcc src-file.c -lm -lpthread
  The libraries referenced in this example for inclusion during linking are the math library and the thread library. They are found in /usr/lib/libm.a and /usr/lib/libpthread.a.

• ld.so - a.out dynamic linker/loader

• Environment variable to highlight warnings, errors, etc: export CC="colorgcc"

• How to generate a library:
  • Compile: cc -c ctest1.c ctest2.c
  • Create library "ctest.a": ar -cvq ctest.a ctest1.o ctest2.o
  • List files in library: ar -t ctest.a
  • Using library: cc -o executable-name prog.c ctest.a
  • Example files:
    • ctest1.c

      ctest1(int *i) { *i=5; }

    • ctest1.c

      ctest1(int *i) { *i=100; }

    • prog.c

      #include <stdio.h> main() { int x; ctest1(&x); printf("Valx=%d\n",x); }

  Historical note: After creating the library it was once necessary to run the command: ranlib ctest.a. This created a symbol table within the archive. Ranlib is now embedded into the "ar" command.

• How to generate a shared object: (Dynamically linked object library file.)

      gcc -fPIC -c *.c
      gcc -shared -Wl,-soname,libfoo.so.1 -o libfoo.so.1.0   *.o
      

  Notes:
  • Option -fPIC: Compiler directive to output position independent code suitable for dynamic linking.
  • Pass options to linker: -Wl.
    In this example the options to be passed on to the linker are: "-soname libfoo.so.1".
  • Option -shared: Produce a shared object which can then be linked with other objects to form an executable.
  • Option -o: Output of operation. In this case the name of the shared object to be output will be "libfoo.so.1.0
  Man Pages:
  • gcc - GNU C compiler
  • ld - The GNU Linker

• Unit test: Testing/Debugging C++ classes (this also applies to C functions)
  Create test main program which by default is not compiled. For debugging and test purposes have the main invoked with a compiler or makefile flag. Implementing this method allows the test program to always be available and in sync with the classes and/or functions within the file.
  See example C++ (ManageNumbers.cpp) program and test case main.
  • Regular compile: g++ -c ManageNumbers.cpp
  • Compile for test: g++ -DMAIN -c ManageNumbers.cpp
  Note: The GNU gcc group often uses the define flag "TEST".

  Create a target in the makefile for the unit test:

  ... testModule1: module1 g++ -DMAIN -c ManageNumbers.cpp ...

  Also see unit test with CppUnit, a C++ Unit test framework

• Internationalization:
  • Message translation see GNU "gettext".
  • If available: ./configure --with-included-gettext
  • Internationalized packages usually have many `po/LL.po' files, where LL gives an ISO 639 two-letter code identifying the language. (i.e. environment variable LANG=en)
  • catgets:
    • ./configure --with-catgets
    • See man page for C function catgets
  • Language codes are NOT the same as the country codes given in ISO 3166.
  • See man page for C functions setlocale, charsets, unicode
  • International character sets: Unicode.org
