Re: Libtool 2.1a ported to SkyOS, how to test?

Hi!






libltdl.dll (A valid SkyOS dll with all functions exported)
libltdl.a (The static library)

========================================================================
libltdl.la :
# libltdl.la - a libtool library file

# It is necessary for linking the library.

# The name that we can dlopen(3).

# Names of this library.

# The name of the static archive.

# Is this an already installed library?

'make install':

Now the questions:






Anyway, a few more information:
I tried to add a skyos target to libtool.m4 with following characteristics:
- The static library should be named: $(libname).a
- The dynamic library should be named: $(libname).dll


I attach following files:
libtool.m4.diff
output from (./bootstrap && ./configure && make && make install)

I would be very thankful for any hint!
Robert!

Ok, made progress. ./bootstrap for libtool-1.5.22 works now. (After fixing the inital stack creation routine and tweaking gcc to return the default library directory for 'gcc -print-search-dirs) But it looks like that there is a misconfiguration in the skyos specific settings I just added. When I try to build libtool-1.5.22 it succeeds and creates following files in the libltdl/.libs directory: # Generated by ltmain.sh - GNU libtool 1.5.22 (1.1220.2.365 2005/12/18 22:14:06) # Generated by ltmain.sh - GNU libtool 1.5.22 (1.1220.2.365 2005/12/18 22:14:06) Unfortunately trying to install libtool-1.5.22 doesn't work because the install process can't find libltdl-3.1.4.dll (which obviously isn't there) /boot/programs/unix/bin/install -c .libs/libltdl.3.1.4.dll $dldir/libltdl.3.1.4.dll (this fails) - Does anyone know which libtool.m4 configuration is responsible for this failure? - When this is fixed, and there finally is a libltdl.3.1.4 dll, does the make install process install a symlink like libltdl.dll -> libltdl.3.1.4.dll ? ( If not, how is ld supposed to find this library when a third party package for instance tries to link to libltdl by just using 'ld -lltdl ?) - May there be any problems with SkyOS using the .PE DLL format for shared libraries? There must be no undefined/unreferenced symbols when building a DLL. (like in Windows) - There should be NO import library. ( $(libname).lib), because SkyOS GCC/LD can directly link against the DLL
