Thread: nmake U1045 error

hi guys, sorry for posting it here, i think its the wrong category but i dont know where else to ask, i searched online for this error and found nothing

im taking a course on compiler design and im trying to do some lexical analysis with flex

i downloaded all the files and there was a makefile in the folder, i need to run nmake in order to create the .c file which will then give me the program which will be doing the lexical analysis

but there is a problem, i found that in order to run nmake i need to run a file called vsvars32.bat

i run the file, then i went to the folder where the makefile is located, i run nmake and i get

"NMAKE : fatal error U1045: spawn failed : No error
Stop."

does anyone know why it gives me this kind of error? i would appreciate any help provided

By the way, I'm using Visual Studio 2008

Yes, i could find nothing.. i tried this You receive a "NMAKE : fatal error U1045: spawn failed : Invalid argument" error message when you compile a makefile by using the Microsoft Program Maintenance utility but it didnt work

it says

"flex nameoffile"

where name of file is the name of the .FILE file that has the C code for flex, its weird because today in the morning our professor showed us the same thing and there was no error, so i doubt that it has anything to do with the code in the .FILE file

it throws me a message telling

"Unsupported 16-bit Application"

The program or feature ...... cannot start or run due to incompatibility with 64-bit Windows versions of Windows. Please contact the software vendor to ask if a 64-bit Windows compatible version is available.

oh... so is this the problem? because in the makefile file there is a call for this flex file i think
