Removing MinGW dll dependencies

libgcc_s_dw2-1.dll

Passing -static-libgcc will remove this dependency for all languages other than C.
Note: C++ exceptions depends on this option.

mingwm10.dll

Remove -mthreads option from your makefile.

How to disable system bell in msys

set bell-style none

Mingw on Linux

I'm using MinGW for years, but never tried to use it on Linux machine as a crosscompiler. Today I've had first experience. First thing I've noticed is how actually easy to install such environment - there is a totally automated build script available from MinGW site.
Pros:

• One environment
• Speed. Native environment vs MSys is much, much faster.

Cons:

• Building non-Linux things on Linux means transferring them from one machine to another.

Gettext compilation on MSys

Trying to build gettext library on MSys I've got some errors related to pthread. Included readme states you need to have Cygwin for that. For those, who prefer MSys over Cygwin here goes a quick fix:

./configure

Add -lpthread to LIBS section in gettext-runtime/src/Makefile and gettext-tools/src/Makefile.
Remove tests target from gettext-runtime/Makefile and gettext-tools/Makefile.

make; make install

Be happy.

Libiconv compilation sed on msys error

Trying to build libiconv library under msys environment, I've got sed related errors:

sed: -e expression #2, char 32: Extra characters after command

Fortunately, I've found a solution in the internet:

Create MinGW library from dll

For this, you need pexports tool from mingw-utils.

pexports library.dll > library.def
dlltool -D library.dll -d library.def -l library.dll.a

Note, that if dll was built by different environment than gcc, this probably will not work because of the naming conventions. If this the case, read here.
