what can I do in this case? it was compiling so nicely, and it was so fast, and then from one moment to the other, I don't know why, I get only one error. gpc: Internal GPC problem: internal option `--amtmpfile' not given gpc1.exe: C:\dev_gpc\bin\gpc exited with status 1 gpc1.exe: C:\dev_gpc\bin\gpc exited with status 1 exiting from Dev+GPC and ree-ntering the project is a no go either. the button: Build all AND the button: make project both buttons deliver the same error message. what can I do.
