cygwin 환경에서 git실행 시 아래와 같은 오류가 발생했다.
$ git clone https://주소

cygwin FAQ에 해결 방법이 나와 있다. 내 환경에서는 rebaseall명령으로 해결되었다.
최근 cygwin을 다시 설치하고 curl을 실행했더니 아래와 같은 오류가 발생했다.
$ curl /usr/bin/curl.exe: error while loading shared libraries: ?: cannot open shared object file: No such file or directory
ldd을 이용해서 설치되지 않은 라이브러리를 찾던 도중 cygcurl-4.dll에서 아래와 같은 무수한 ???를 만나게 되었다.

???의 정체를 알기 위해 구글링해본 결과 cygcheck을 사용해보라는 글이 있어서 cygcheck을 사용해 보았다.

link 옵션에 아래 내용 추가
--target=i686-pc-mingw32 -mno-cygwin
cygwin/gcc 3.4.4 에서는 -mno-cygwin 옵션을 주면 링크 에러가 난다. 해결책은 아래 링크에 있다
http://www.hotsolder.com/labels/cygwin.html
만일을 위해 일부를 발췌해 놓는다.
1) In /usr/lib/gcc there is a directory for i686-pc-mingw32/3.4.4. In that directory, the Cygwin installer put ordinary .lnk files linking back to /usr/lib/gcc/i686-pc-cygwin/3.4.4. None of these work, so the first step is to make hard or symbolic links to the correct files. For example, cc1.exe.lnk needs to be fixed (from the i686-pc-mingw32/3.4.4 directory):
ln ../i686-pc-cygwin/cc1.exe cc1.exe
Fix all the links in this way. Now gcc will run with -mno-cygwin, but it still won't link. 2) The problem is, gcc is a driver and the specs file is broken. In the same directory, edit the file named specs. The trick here is we need to change the references to crt2.o to refer to a specific path (/usr/lib/mingw/crt2.0). We also need to add -L/usr/lib/mingw to several places. Here's a diff between the standard specs file and mine (significant additions in red):
$ diff specs ../../i686-pc-cygwin/3.4.4/specs
