Google code hosted C++ projects

Here is short list of IMHO interesting projects hosted at google code (C++ only)

• googlemock
• googletest
• google-glog
• gflags
• checkheaders
• sqlite3pp
• protocol-buffers

linking and optimization

Some info regarding shared libraries and link optimization (just not to forget).

Command to check library's specific headers, e.g. library "soname" and required library and their versions:
objdump -p libXXX.so

To display exported symbols:
nm -g -D -C --defined-only libXXX.so

Some makefile macros to create shared library:
LIB_LINKER_NAME := libXXX.so
LIB_VERSION_MAJOR := 1
LIB_VERSION_MINOR := 1
LIB_SONAME_NAME := $(LIB_LINKER_NAME).$(LIB_VERSION_MAJOR)
LIB_REAL_NAME := $(LIB_SONAME_NAME).$(LIB_VERSION_MINOR)
$(CC) -shared -o $(LIB_REAL_NAME) $(OBJ) -L$(LIB_DIR) $(LIBS) -Wl,-soname=$(LIB_SONAME_NAME) -Wl,--version-script=XXX.expmap

Export map file for shared library:
XXX.expmap:
{
  global:
    fun1;
    fun2;

  local:
    *;
};
