Make: *** [lib/libCintex.so] Error

ROOT
1

hello,
i have been trying to install root 5.14 with gcc 3.4 by forcing the computer to use that version of gcc (sudo rm /usr/bin/gcc sudo ln -s /usr/bin/gcc-3.4 /usr/bin/gcc) i did the same for cpp g77 and g++. Anyway i still have this problem :

sudo ./configure
sudo make
…
collect2: ld returned 1 exit status
make: *** [lib/libCintex.so] Error 1

i hope this does not come from the fact that these librairies have been compiled with gcc 4.2.3 and that now that i changed gcc smthing goes wrong with them!!!
could anybody help me?
cheers,
dounia.

Yes this indicates that there i a problem with the compilation (i.e. different part compiled with different version of the compiler and/or the compiler/system library are not the right onces …)

okay but i don`t know which librairies have been compiled with which compiler. Actually i already installed root 5.14 and 5.18 on this computer with the other compilers i just deleted my root dir to install it again with gcc 3.4 but i guess it is not enough but could not find the uninstall thing…
do you know if i can solve this?

when i dont sudo first and just type make i get this :

dounia@ordinator:~/gate/root$ make
g++ -shared -Wl,-soname,libCintex.so -m32 -O -o lib/libCintex.so cintex/src/CINTClassBuilder.o cintex/src/CINTEnumBuilder.o cintex/src/Cintex.o cintex/src/CINTFunctional.o cintex/src/CINTFunctionBuilder.o cintex/src/CINTScopeBuilder.o cintex/src/CINTTypedefBuilder.o cintex/src/CINTUtils.o cintex/src/CINTVariableBuilder.o cintex/src/ROOTClassEnhancer.o
/usr/bin/ld: cannot open output file lib/libCintex.so: Permission denied
collect2: ld returned 1 exit status
make: *** [lib/libCintex.so] Error 1

dont if this could help…

[quote]do you know if i can solve this?[/quote]First you need to make sure that you technique to install the older compiler is sound … " ln -s /usr/bin/gcc-3.4 /usr/bin/gcc" seems insufficient to me (their is possibly compiler library in /usr/lib and header file in /usr/include). Please refer to the gcc documentation and/or a local expert on gcc installation.

okay but i can`t find anything on gcc website.
i put also
rm /usr/bin/i486-linux-gnu-g++
ln -s /usr/bin/i486…g+±3.4 /usr/bin/i486…g++

but you are certainly right this might not be enough…
I did not really get the exact problem with root actually. Could you explain?
thank you.

the libCintex.so library error… is that really that this librairy for example has been compiled with the newer version of gcc? isnt`it possible to remove anything from root and install it again with the right compiler?
i will ask about gcc on the gcc forum…

[quote]isnt`it possible to remove anything from root and install it again with the right compiler? [/quote]Assuming the right compiler is set :slight_smile:, you can easily recompile cintex via:gmake clean-cintex gmake

Cheers,
