Hi Natalie,

Did you see if you can configure libtpp with --disable-shared?

The simplest link test is probably to remove the --disable-bsdtar
option from libarchive's configure. Then we can look through the log
to see how it builds bsdtar.exe. The -DLIBARCHIVE_STATIC option to gcc
seems to do the trick.

Try compiling the test program with a line like:

i686-pc-mingw32-gcc -o libarchive-test.exe libarchive-test.c \
`i686-pc-mingw32-pkg-config libarchive --cflags --libs` \
-DLIBARCHIVE_STATIC

and you should get no errors, though this doesn't seem ideal.



Hi Volker,

Do you think it's reasonable to build bsdtar.exe as a link test then
write a simple batch file as a runtime test?
