[Ecls-list] ecl-0.9e msvc 7.1 linker error (windows).

[Valery Syssik]

Good evening, Giuseppe Attardi.
Tanks for maintenance and support ECL!

Good evening, all list subscribers.

I try to build ECL (ecl-0.9e-fix-1.tgz.gz)
under MSVC 7.1 (VS.NET 2003) on my Windows 2000 box today.

Linking failed twice on "ecl_min.exe" and "ecl.dll",
because there is a mixture of libc and libcd (debug)
libraries used inside *.obj files.

nmake -f Makefile.msvc6 >out1 2>out2
"out1" file:
-----
#At first used "/ML" (Single-Threaded) compiler option.
echo > msvc-build
cl -c /nologo /ML /W3 /GX /I "." /I ..\..\src\gmp /I "..\..\src\gmp\mpn\generic" /D "WIN32" /D "NDEBUG" /D "_LIB" /D "_WIN32" /D "_MBCS" /Fompn\generic\add.obj ..\..\src\gmp\mpn\generic\add.c

#In "gc" directory used "/MLd" (Debug Single-Threaded) compiler option.

 cd gc
 nmake -f Makefile.msvc6 gc.lib

Then any run-time library option skipped (compiler’s default action: /ML)

I linked it manually via command line
cl -Zi /Feecl_min.exe cinit.obj c\all_symbols.obj eclmin.lib eclgc.lib eclgmp.lib user32.lib ws2_32.lib /link "/NODEFAULTLIB:libc"

cl -Zi -Fe"ecl.dll" "c/main.obj" "c/all_symbols2.obj" "lsp.lib" "eclmin.lib"  /LD /link /LIBPATH:"H:/src/ecl-0.9e/msvc/" eclgmp.lib eclgc.lib user32.lib ws2_32.lib /DEF:ecl.def /link /NODEFAULTLIB:libc"


Can anybody (please) explain what version of C run-time should be used,
and how to fix this problem correctly.

The second question is:
What does it mean:  "Threads were broken with latest
improvements." (http://ecls.sourceforge.net/news.html)?

Can ECL used in MT program with POSIX threads (Solaris) and
Windows threads?

Best regards,
Valery Syssik.
