Does MinGW influence compilation — a GTK program

阅读更多关于 Does MinGW influence compilation — a GTK program

问题 I compiled a GTK program in MinGW environment. It worked perfect. Recently, I updated MinGW and recompiled the GTK program, then the program always stopped with Segmentation fault. I have tried to use gdb to look for errors but I couldn't. The config of GTK is exactly same in the old and new MinGW. Therefore, I am suspicious of MinGW environment that influences compilation. I found the version of gcc is different in two environment: old MinGW new MinGW gcc 3.4.5 4.7.2 Any idea? Does anybody

问题 I'm trying to create EXE files from a shell script file I'm launching from minggw (used from git bash) My problem is when I run these commands: C:/Windows/system32/iexpress.exe //N C:\\git\\install_64bitWindows.SED C:/Windows/SysWOW64/iexpress.exe //N C:\\git\\Install_32bitWindows.SED They always end up invoking the makecab in SysWOW64 (which creates a 32 bit .exe) Is there anyway for me to launch a new cmd from system32 for me to be able to make my 64 bit .exe? 回答1: Because you're running

Vim behaving weirdly on Mingw

阅读更多关于 Vim behaving weirdly on Mingw

问题 My Vim on MinGW 4.6.2 is behaving weirdly, for example, pressing Backspace in insert mode deletes characters, but I have to move the cursor with arrow keys before the deleted characters disappear, and it also takes me out of insert mode. Another example, pressing Del to delete characters sometimes generates weird characters like changing lowercase characters to uppercase, or corrupts the next character that I key in, for example pressing 'S' gives me '$' initally. Am I using Vim wrong or
