***BOGO*** Re: [Mingw-users] STLport build

[François Dumont <francois.cppdevs@xxxxxxx>]

Hi

I finally successfully built STLport the way I wanted it to be built 
with the following link command:
c++ -Wall -Wsign-promo -Wcast-qual -fexceptions -mthreads -g  
-DWINVER=0x0501 -D_DEBUG -I../../stlport   -shared 
-Wl,--out-implib=obj/gcc/so_g/libstlportg.5.2.dll.a -nodefaultlibs  -o 
obj/gcc/so_g/libstlportg.5.2.dll obj/gcc/so_g/dll_main.o 
obj/gcc/so_g/fstream.o obj/gcc/so_g/strstream.o obj/gcc/so_g/sstream.o 
obj/gcc/so_g/ios.o obj/gcc/so_g/stdio_streambuf.o obj/gcc/so_g/istream.o 
obj/gcc/so_g/ostream.o obj/gcc/so_g/iostream.o obj/gcc/so_g/codecvt.o 
obj/gcc/so_g/collate.o obj/gcc/so_g/ctype.o obj/gcc/so_g/monetary.o 
obj/gcc/so_g/num_get.o obj/gcc/so_g/num_put.o 
obj/gcc/so_g/num_get_float.o obj/gcc/so_g/num_put_float.o 
obj/gcc/so_g/numpunct.o obj/gcc/so_g/time_facets.o 
obj/gcc/so_g/messages.o obj/gcc/so_g/locale.o obj/gcc/so_g/locale_impl.o 
obj/gcc/so_g/locale_catalog.o obj/gcc/so_g/facets_byname.o 
obj/gcc/so_g/complex.o obj/gcc/so_g/complex_io.o 
obj/gcc/so_g/complex_trig.o obj/gcc/so_g/string.o obj/gcc/so_g/bitset.o 
obj/gcc/so_g/allocators.o obj/gcc/so_g/c_locale.o obj/gcc/so_g/cxa.o 
obj/gcc/so_g/stlport.res  -Wl,-whole-archive -lsupc++  
-Wl,-no-whole-archive -lgcc -lm -lmoldname -lmingw32 -lmingwex -lmsvcrt 
-lkernel32

However I am still experimenting an issue. Despite I used 
-Wl,-whole-archive when linking libsupc++ I still have to specify it 
when linking an exec using STLport. Is this linker option not supported 
when using MinGW ? An other problem that I was expecting is that when 
running STLport unit tests each time an exception is thrown the 
application stop signaling it. As exception support been restored in 
latest experimental package ?

For your info I am using gcc 4.2.1 from an old experimental package 
granted on MinGW souceforge download page, I will try latest 
experimental package tomorrow.
