I saw a discussion that looked exactly like the issue that I'm having, but turned out to be a divide by zero error instead. I apologize if this issue as already been addressed. I am trying to run an IDE called MPLAB(v7.20) under wine(v20050524). I can get the IDE up and it will successfully call another program called mpasmwin.exe which assembles the file. This mpasmwin program generates some output files and quits, but the output messages never make it back to the MPLAB IDE. After about 10 seconds, MPLAB outputs: Thread would not exit normally. Could not read language tool output from pipe. (5) I ran the following command as it was suggested to in the other thread that I read: ~/.wine/c$ WINEDEBUG=+process,+exec wine ./Programme/Microchip/MPLAB\ IDE/Core/MPLAB.exe and got this: trace:process:init_current_directory starting in L"C:\\" 0x10 trace:process:find_exe_file looking for L"./Programme/Microchip/MPLAB IDE/Core/MPLAB.exe" trace:process:find_exe_file Trying native exe L"C:\\Programme\\Microchip\\MPLAB IDE\\Core\\MPLAB.exe" trace:process:__wine_kernel_init starting process name=L"C:\\Programme\\Microchip\\MPLAB IDE\\Core\\MPLAB.exe" file=0x18 argv[0]="./Programme/Microchip/MPLAB IDE/Core/MPLAB.exe" trace:process:__wine_kernel_init starting Win32 binary L"C:\\Programme\\Microchip\\MPLAB IDE\\Core\\MPLAB.exe" trace:process:CreateProcessW app (null) cmdline L"\"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE\" /q /p18F8722 \"bttn.asm\" /l\"bttn.lst\" /e\"bttn.err\" /o\"bttn.o\" /x\"bttn.xrf\"" trace:process:find_exe_file looking for L"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" trace:process:find_exe_file Trying native exe L"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" trace:process:CreateProcessW starting L"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" as Win32 binary (0x400000-0x8f2000) trace:process:init_current_directory starting in L"H:\\projects\\pic\\demos\\bttn.zip_FILES\\" 0x14 trace:process:__wine_kernel_init starting process name=L"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" file=0x10 argv[0]="C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" trace:process:__wine_kernel_init starting Win32 binary L"C:\\Program Files\\Microchip\\MPASM Suite\\MPASMWIN.EXE" fixme:font:load_VDMX Failed to retrieve vTable Everything looks great to me. No mention is made of pipes or failed output or anything. These messages are all that were generated and the output window in MPLAB reported the pipe error as stated above. I've been in contact with Microchip to try and figure out how MPLAB and MPASMWIN are communicating so I could get a little better idea of what to look for, but haven't heard back anything. Any ideas? Thanks in advance. Johnny Cybermyth _______________________________________________ wine-users mailing list wine-users@xxxxxxxxxx http://www.winehq.org/mailman/listinfo/wine-users
