HiI'm new to this but know that MS Flight Simulator would one need little tweak to run flight school etc. (already worked once)So I've downloaded git and would be thankful for hints on how to proceed and find those bugs in FS9. I also would prefer using Eclipse/Linux, but anyway thanks for help.Many thanksMichael

Unsure about Redhat. Ciao, Marcus

Many thanks Michael hi michael! if it has already worked before you need to do some regression testing to see when the new error was introduced. http://wiki.winehq.org/RegressionTesting http://wiki.winehq.org/RegressionTestingas far as using eclipse or whatever that's your choice. use what you feel confortable with to compile and test code. have fun :)
disabling FORTIFY_SOURCE
Hi, It seems to me that disabling FORTIFY_SOURCE is a mistake. It offers a great many protections, and virtually every distribution has very intentionally turned on this compiler flag by default. Given Wine's size[1], I would argue the benefits[2] outweigh the hassle of rearranging the structures and accessors to not trick the compiler into allocating memory beyond the end of the structure for incoming strings. It has found, at least in other projects, a lot of potential problems, and better yet, has repeatedly turned exploitable vulnerabilities into simple denial of services. I realize it's a bit of a pain to work with given how you're building some of the structures, but I'd like to ask that it not be globally disabled. Thanks, -Kees [1] $ find . -type f -name '*.[ch]' | xargs wc -l | grep total 2678911 total [2] Some details at https://wiki.ubuntu.com/CompilerFlags#-D_FORTIFY_SOURCE=2 but at least the following...

re: disabling FORTIFY_SOURCE
Hi Kees, sure, supporting Fortify in Wine would be great, but it's not clear how long it will take to fix Wine so it works with Fortify. Which would you prefer: 1) have Wine broken for an unknown and possibly long time or 2) have Wine working, but without Fortify, until the bugs are fixed ?
