Egor, I am grateful to you, the author of this book, and the whole CYGWIN community to provide such a useful information like this. I downloaded this book, read it a little, could not wait apprciating this and so I am sending this email.

I am surprised you answered so quickly ( and most grateful as well). Hope to contribute something of use in the future and keep up the good work. I really love cygwin. I am a c++ programmer by trade, but unemployed due to the WTC disaster. Thanks again, and have a very good holiday season.

Thank you in advance for your time. the format of files generated by gcc depends on platform. it's ELF for linux/freebsd/a bunch of other unices, COFF for windows, etc. windows can't run ELF binaries, and gcc provided with cygwin is intended to produce windows executables. if you want to build ELF executables for, say, linux, you should build gcc as cross-compiler. I'd suggest an excellent book "Linkers and loaders" by John Levine (you can download a draft from http://www.iecc.com/linker/) -- it describes in great detail how all those things work. a good introduction to cross-compilation stuff can be found at http://www.airs.com/ian/configure/ Egor. mailto:[EMAIL PROTECTED] ICQ 5165414 FidoNet 2:5020/496.19 -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
