Overview
cprobe
cprobe is a portable script that reliably probes a compiler to get the following properties:
- compiler command (if not specified on command line)
- compiler type
- compiler version
- C/C++ language standard
- target OS
- target OS version,
- target architecture
- target bitness
- target endianess
- target data model
- POSIX support version
- SUS support version
- if compiler is cross-compiler
- if compiler is C++ compiler
Example:
$ cprobe type: gcc version: 4.9.2 command: gcc C standard: c89 C++ standard: cxx98 target os: gnulinux target os version: - target arch: x86_64 bitness: 64 endianness: little data model: lp64 cross compiler: false C++ compiler: true posix version: posix1-2008 sus version: susv4 $ cprobe clang type: clang version: 3.5.0 command: clang C standard: c99 C++ standard: cxx98 target os: gnulinux target os version: - target arch: x86_64 bitness: 64 endianness: little data model: lp64 cross compiler: false C++ compiler: true posix version: posix1-2008 sus version: susv4 $ cprobe x86_64-w64-mingw32-gcc type: gcc version: 4.9.1 command: /usr/bin/x86_64-w64-mingw32-gcc C standard: c89 C++ standard: cxx98 target os: windows target os version: - target arch: x86_64 bitness: 64 endianness: little data model: llp64 cross compiler: true C++ compiler: true posix version: - sus version: - $ cprobe g++ -lang=c++11 -msse4 -O3 -g2 -I. -Wall type: gcc version: 4.9.2 command: g++ C standard: c89 C++ standard: cxx98 target os: gnulinux target os version: - target arch: x86_64 bitness: 64 endianness: little data model: lp64 cross compiler: true C++ compiler: true posix version: posix1-2008 sus version: susv4 $ cprobe -f4 gcc:gnulinux:x86_64:gcc $ cprobe -f5 gcc:4.9.2:c89:cxx98:gnulinux::x86_64:64::lp64:false:true:posix1-2008:susv4:gcc $ cprobe gcc -f1 CC_CMD="gcc" CC_TYPE="gcc" CC_VERSION="4.9.2" CC_STD="c89" CC_CXX_STD="cxx98" CC_OS="gnulinux" CC_OS_VERSION="" CC_ARCH="x86_64" CC_BITNESS="64" CC_ENDIANNESS="little" CC_DATA_MODEL="lp64" CC_FLAG_CROSS="false" CC_FLAG_CXX="true" CC_POSIX="posix1-2008" CC_SUS="susv4"
cltest
cltest can test compiler, compiler flags, system libraries and other C/C++ system properties. If you need to check system for any C/C++ dependencies, cltest tool is what you need.
Example:
$ cltest checking compiler gcc ... OK checking linker gcc ... OK $ cltest clang checking compiler clang ... OK checking linker clang ... OK $ cltest -I. -DVERSION=1.0 -UDEBUG -L. -O3 -g0 checking compiler flags -I. -DVERSION=1.0 -UDEBUG -O3 -g0 ... OK checking linker flags -L. -O3 -g0 ... OK $ ./cltest -lxml2 -lm stdio.h stdlib.h stdarg.h checking header stdio.h ... OK checking header stdlib.h ... OK checking header stdarg.h ... OK checking libraries -lxml2 -lm ... OK $ cltest clang "#ifdef __clang_major__" -def="__unix__ __linux__" checking define #ifdef __clang_major__ ... OK checking define __unix__ ... OK checking define __linux__ ... OK $ cltest "fprintf()" "atoi()" =__SIZEOF_INT__ stdio.h errno.h -var="errno sys_errlist" checking variable errno ... OK checking variable sys_errlist ... OK checking rval __SIZEOF_INT__ ... OK checking function fprintf ... OK checking function atoi ... OK $ cltest "xmlXPathInit() xmlListWalk() xmlAddChild()" -lxml2 checking function xmlXPathInit ... OK checking function xmlListWalk ... OK checking function xmlAddChild ... OK $ cltest g++ -lQtGui checking libraries -lQtGui ... OK
cltest can test the following properties:
- compiler/linker. check if compiler/linker works
- compiler/linker flags. check if given flags are correct for the specified or autoselected compiler
- libraries. check if given libraries are available on a system
- headers. check if given headers are available on a system
- defines. test specified defines and complex macro commands
- types. check if specified types are available
- enum constants
- extern variables
- functions
- symbols
- rvalues
- one line source strings
- custom source files. Check given source files
cppdef
cppdef is a simple tool to read CPP defines. It is very useful in 'configure' scripts to check specific compiler or system library properties. Example:
$ cppdef __GNUC__ 4 $ cppdef -cc=clang __clang_major__ 3 $ ./cppdef LIBXML_VERSION_STRING -I/usr/include/libxml2 libxml/xmlversion.h 20901
mkdep
Tool to generate dependencies of C/C++ source files for Makefile. mkdep is portable and compiler-independent.
Example for simple source file 'file1.c':
$ mkdep gcc -o obj/file1.o -c file1.c -I. -g0 -O3 >file.d $ cat file1.d obj/file1.o: file1.c /usr/include/stdc-predef.h /usr/include/stdio.h \ /usr/include/features.h /usr/include/x86_64-linux-gnu/sys/cdefs.h \ /usr/include/x86_64-linux-gnu/bits/wordsize.h \ /usr/include/x86_64-linux-gnu/gnu/stubs.h \ /usr/include/x86_64-linux-gnu/gnu/stubs-64.h \ /usr/lib/gcc/x86_64-linux-gnu/4.9/include/stddef.h \ /usr/include/x86_64-linux-gnu/bits/types.h \ /usr/include/x86_64-linux-gnu/bits/typesizes.h /usr/include/libio.h \ /usr/include/_G_config.h /usr/include/wchar.h \ /usr/lib/gcc/x86_64-linux-gnu/4.9/include/stdarg.h \ /usr/include/x86_64-linux-gnu/bits/stdio_lim.h \ /usr/include/x86_64-linux-gnu/bits/sys_errlist.h /usr/include/stdc-predef.h: /usr/include/stdio.h: /usr/include/features.h: /usr/include/x86_64-linux-gnu/sys/cdefs.h: /usr/include/x86_64-linux-gnu/bits/wordsize.h: /usr/include/x86_64-linux-gnu/gnu/stubs.h: /usr/include/x86_64-linux-gnu/gnu/stubs-64.h: /usr/lib/gcc/x86_64-linux-gnu/4.9/include/stddef.h: /usr/include/x86_64-linux-gnu/bits/types.h: /usr/include/x86_64-linux-gnu/bits/typesizes.h: /usr/include/libio.h: /usr/include/_G_config.h: /usr/include/wchar.h: /usr/lib/gcc/x86_64-linux-gnu/4.9/include/stdarg.h: /usr/include/x86_64-linux-gnu/bits/stdio_lim.h: /usr/include/x86_64-linux-gnu/bits/sys_errlist.h:
