[LLVMdev] [LLVMDev] trouble building gcc-frontend from source
Hi all, I am a new user of LLVM, and wanted to explore it in conjunction with the compilers course I am taking in my university. To this end, I downloaded the code for the LLVM suite and the LLVM-gcc front end from the respective repositories. Then, I built the LLVM suite without any hitch, but when I tried to build the llvm-gcc frontend (exactly following the instructions of README.LLVM) , I got compilator errors. I am using "gcc (GCC) 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2)" on Ubuntu 7.10, Intel Core Duo. I have attached the make file output with this mail. (I did not find any mention of this mailing list's policy on attachments, and if it's against the rules then I apologise). I wished to know if the error is a result of some recent changes taking place in the code and if using the pre-compiled binaries will help, or is there something wrong at my end?

Hello,> I wished to know if the error is a result of some recent changes > taking place in the code and if using the pre-compiled binaries will > help, or is there something wrong at my end?It seems, that your llvm and llvm-gcc sources are out of sync. PS: gcc 4.1.x is know to be the source of all sorts of miscompilations, I don't know whether it's still true for 4.1.3, but definitely so fo 4.1.2 --- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

Hi, the versions of llvm-gcc and llvm you are using are not synchronized. Probably one is from subversion while the other is not. Ciao, Duncan.

Since it didn't, I guess you made a mistake when trying to use gcc-4.2 and g++-4.2 and actually used the 4.1 versions instead. Ciao, Duncan.
