I want to create a library (Ubuntu, shared or static) from C++ source code. The given source code includes a main() function in "outFile.cpp".
I want to write my own main.cpp file that should be linked to the library like "g++ -lMyLibrary.a" lateron.
Therefore, I want to modify the build script for the C++ source code. What in the build script below do I need to modify in order to generate a library file, excluding any main() function and that provides me all the functions/methods from the source code?
The buildscript uses automake.
buidScript.sh :
#!/bin/bash
./autogen.sh ;
./autogen.sh ;
export CXXFLAGS="-O2"
export CFLAGS="-O2"
export CPPFLAGS="-D__STATIC_LINK -DBUILD_WITH_GPL3rdP -DBUILD_LIBSVM ...."
./configure --prefix=$INSTPREFIX --enable-static --enable-shared=no
./update_build_version.sh
make clean &&
make -j8 ; make install
g++ $CFLAGS -static -o outFile outFile-outFile.o -lm -pthread .libs/libMyLibrary.a
Makefile.am:
ACLOCAL_AMFLAGS = -I m4
AUTOMAKE_OPTIONS = subdir-objects
bin_PROGRAMS = outFile
...
NEWMAT_SOURCES=\
NEWMAT_CPPFLAGS = -I ../thirdparty
NEWMAT_LDFLAGS =
LIB_SOURCES=\
lib_LTLIBRARIES = libMyLibrary.la
libMyLibrary_la_SOURCES = $(MyLibrary_SOURCES)
libMyLibrary_la_CPPFLAGS = $(MyLibrary_CPPFLAGS)
libMyLibrary_la_LIBADD = $(MyLibrary_LIBS)
libMyLibrary_la_LDFLAGS = --no-undefined
Sorry for the weak description, its the first build script I write and I'm still reading about the necessary tools. Thanks.
