Hello, Today i installed cygwin to compile a windows .exe out of a Linux source program. While G++ on Linux compiles it correctly into a binary, on cygwin i got an issue during linking:
$ g++ -O2 -Wall -Isrc -o bin/sealtool <SNIP> src/sign-verify.cpp -lcrypto -lssl -lcurl -lresolv /usr/lib/gcc/x86_64-pc-cygwin/12/../../../../x86_64-pc-cygwin/bin/ld: /tmp/ccA3GExv.o:sign-verify.cp:(.text+0x437): undefined reference to `__ns_initparse' /usr/lib/gcc/x86_64-pc-cygwin/12/../../../../x86_64-pc-cygwin/bin/ld: /tmp/ccA3GExv.o:sign-verify.cp:(.text+0x49a): undefined reference to `__ns_parserr' collect2: error: ld returned 1 exit status >From looking at the nm results, the provided libresolv library does not >include these symbols. (But my linux distro's version of libresolv DOES have them!) Does anyone know why these symbols are missing? (and more importantly, how do i get them?) The internet didn't yield me any answers. libresolv.a is included with cygwin-devel-3.5.4-1, so i can't really check or change it's version. (md5sum is 5fa4735707cec921f81feb2c86c5b87a) The source file i try to compile can be found at https://github.com/hackerfactor/SEAL-C/blob/main/src/sign-verify.cpp , project has other issues which i already had resolv. ;) At the very least, thanks for reading!
