|
|
|
- * This is a crude wrapper to use uClibc with gcc.
|
|
|
- * It was originally written to work around ./configure for ext2fs-utils.
|
|
|
- * It certainly can be improved, but it works for me in the normal cases.
|
|
|
- *
|
|
|
- * April 7, 2001
|
|
|
- *
|
|
|
- * A bug was fixed in building the gcc command line when dynamic linking.
|
|
|
- * The functions dlopen, etc. now work. At this time, you must make sure
|
|
|
- * the correct libdl.so is included however. It is safest to, for example,
|
|
|
- * add /lib/libdl.so.1 if using ld-linux.so.1 rather than adding -ldl to the
|
|
|
- * command line.
|
|
|
- *
|
|
|
- * Note: This is only a problem if devel and target archs are the same. To
|
|
|
- * avoid the problem, you can use a customized dynamic linker.
|
|
|
- *
|
|
|
- *
|
|
|
- * April 18, 2001
|
|
|
- *
|
|
|
- * The wrapper now works with either installed and uninstalled uClibc versions.
|
|
|
- * If you want to use the uninstalled header files and libs, either include
|
|
|
- * the string "build" in the invocation name such as
|
|
|
- * 'ln -s <ARCH>-uclibc-gcc <ARCH>-uclibc-gcc-build'
|
|
|
- * or include it in the environment variable setting of UCLIBC_ENV.
|
|
|
- * Note: This automatically enables the "rpath" behavior described below.
|
|
|
- *
|
|
|
- * The wrapper will now pass the location of the uClibc shared libs used to
|
|
|
- * the linker with the "-rpath" option if the invocation name includes the
|
|
|
- * string "rpath" or if the environment variable UCLIBC_ENV include it (as
|
|
|
- * with "build" above). This is primarily intended to be used on devel
|
|
|
- * platforms of the same arch as the target. A good place to use this feature
|
|
|
- * would be in the uClibc/test directory.
|
|
|
- *
|
|
|
- * The wrapper now displays the command line passed to gcc when '-v' is used.
|
|
|
- *
|
|
|
- * May 31, 2001
|
|
|
- *
|
|
|
- * "rpath" and "build" behavior are now decoupled. You can of course get
|
|
|
- * the old "build" behavior by setting UCLIBC_ENV="rpath-build". Order
|
|
|
- * isn't important here, as only the substrings are searched for.
|
|
|
- *
|
|
|
- * Added environment variable check for UCLIBC_GCC_DLOPT to let user specify
|
|
|
- * an alternative dynamic linker at runtime without using command line args.
|
|
|
- * Since this wouldn't commonly be used, I made it easy on myself. You have
|
|
|
- * to match the option you would have passed to the gcc wrapper. As an
|
|
|
- * example,
|
|
|
- *
|
|
|
- * export UCLIBC_GCC_DLOPT="-Wl,--dynamic-linker,/lib/ld-alt-linker.so.3"
|
|
|
- *
|
|
|
- * This is really only useful if target arch == devel arch and DEVEL_PREFIX
|
|
|
- * isn't empty. It involves a recompile, but you can at least test apps
|
|
|
- * on your devel system if combined with the "rpath" behavor if by using
|
|
|
- * LD_LIBRARY_PATH, etc.
|
|
|
- *
|
|
|
- * Also added check for "-Wl,--dynamic-linker" on the command line. The
|
|
|
- * use default dynamic linker or the envirnment-specified dynamic linker
|
|
|
- * is disabled in that case.
|
|
|
- *
|
|
|
- * Added options --uclibc-use-build-dir and --uclibc-use-rpath so that those
|
|
|
- * behaviors can be invoked from the command line.
