Hi, Regarding https://cygwin.com/packages/summary/gcc-g++.html This is a (perhaps) esoteric question about how gnu gcc should operate. It says at https://gcc.gnu.org/onlinedocs/cpp/Search-Path.html "By default, the preprocessor looks for header files included by the quote form of the directive #include "file" first relative to the directory of the current file," When building boost C++ libraries on an earlier version of cygwin this used to work fine. Now, updating to a newer cygwin version on Appveyor, "APPVEYOR_BUILD_WORKER_IMAGE: Visual Studio 2019" , it has broken..
Errors appear such as "fatal error: zutil.h: No such file or directory 8 | #include "zutil.h" compilation terminated." "No such file or directory." What do you think? It can't find the header file, which happens to be in the same directory, the current directory. It seems like a bug, however, if it's intended behavior, and the current directory has been removed from the search path, then could a command-line flag be provided to optionally re-enable the previous functionality? -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
