expands to a full path name. Substitute $outputname.exp" instead and it makes a viable temporary file name. This gets around the problem with lli on Cygwin linking but not having any "C" library functions linked into it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@19123 91177308-0d34-0410-b5e6-96231b3b80d8

Upgrading Libtool
|
|
===============================================================================
|
|
|
|
If you are in the mood to upgrade libtool, you must do the following:
|
|
|
|
1. Get the new version of libtool and put it in <SRC>
|
|
2. configure/build/install libtool with --prefix=<PFX>
|
|
3. Copy <SRC>/ltdl.m4 to llvm/autoconf/m4
|
|
4. Copy <PFX>/share/aclocal/libtool.m4 to llvm/autoconf/m4/libtool.m4
|
|
5. Copy <PFX>/share/libtool/ltmain.sh to llvm/autoconf/ltmain.sh
|
|
6. Run sed -e 's/output.exp/outputname.exp/g' on ltmain.sh
|
|
7. Copy <PFX>/share/libtool/libltdl/ltdl.c to llvm/lib/System
|
|
8. Copy <PFX>/share/libtool/libltdl/ltdl.h to llvm/lib/System
|
|
9. Adjust the llvm/autoconf/m4/libtool.m4 file to ensure that the variable
|
|
default_ofile is set to "mklib" instead of "libtool"
|
|
10. Run "autoupdate libtool.m4 ltdl.m4" in the llvm/autoconf/m4 directory.
|
|
This should correctly update the macro definitions in the libtool m4
|
|
files to match the version of autoconf that LLVM uses. This converts
|
|
AC_HELP_STRING to AS_HELP_STRING and AC_TRY_LINK to AC_LINK_IFELSE, amongst
|
|
other things. You may need to manually adjust the files.
|
|
11. Run AutoRegen.sh to get the new macros into configure script
|
|
12. If there are any warnings from configure, go to step 9.
|
|
13. Rebuild LLVM, making sure it reconfigured
|
|
14. Test the JIT which uses libltdl
|
|
15. If it all works, only THEN commit the changes.

Upgrading autoconf
|
|
===============================================================================
|
|
|
|
If you are in the mood to upgrade autoconf, you should:
|
|
|
|
1. Consider not upgrading.
|
|
2. No really, this is a hassle, you don't want to do it.
|
|
3. Get the new version of autoconf and put it in <SRC>
|
|
4. configure/build/install autoconf with --prefix=<PFX>
|
|
5. Run autoupdate on all the m4 macros in llvm/autoconf/m4
|
|
6. Run autoupdate on llvm/autoconf/configure.ac
|
|
7. Regenerate configure script with AutoRegen.sh
|
|
8. If there are any warnings from autoconf, fix them and go to step 7.
|
|
9. Test, test, test.
