Yesterday I did _not_ make from the root directory. When I try to do a make from the root I get an error when cinstall tries to compile zlib. (CC_FOR_TARGET) -DPACKAGE=\"zlib\" -DVERSION=\"1.1.3\" -DHAVE_UNISTD_H=1 -DHAVE_GETPAGESIZE=1 -DHAVE_MEMCPY=1 -DHAVE_STRERROR=1 -DHAVE_UNISTD_H=1 -I. -I../../../../../src/winsup/cinstall/zlib -I../../../../../src/winsup/cinstall/zlib/.. -g -O2 -W -Wall -mno-c ygwin -I../../../../src/winsup/mingw/include -I../../../../src/winsup/w32api/include -c ../../../../../src/winsup/cinstall/zlib/gzio.c Syntax error: word unexpected Notice the missing '$'? I looked at the Makefile.in files yesterday and did not see an obvious reason for this. If I move down a level to winsup, I get past this error. Then I get the __errno error. >From: Chris Faylor > >>Can you try doing a "make clean all" in the cinstall directory and see > >>if that "fixes" things? No luck.

I am using the canned specs and everything else from the net preview. And a separate question, when commit'ing a change to configure.in, do I also update the configure file itself? I would assume so, but thought I should what ask the approved version of autoconf was before I overwrite a version 31.415 file with a version 0.1a file. ;^) I know as-yet-unreleased tools are frequently used on this project. Thank you all for your patience. I am a little out of my realm of expertice with some of these problems, but I learn very quickly. It will be worth it in the long run as I broaden my understanding and am able to make further contributions to the cygwin project. ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
