gcc installation and make

MonderS · 02-03-2009, 09:58 AM

Sorry to bother you with this but i am hitting a brick wall and cant realy figure it out and was told you guys are the best around and if anyone can help me it would be on linuxQ.

i am running rhl e5 which comes with gcc4.1 and gcc++4.1. i am trying to compile an application that needs gcc-3.2, i have installed compat.gcc32 and compat-gcc-g++32. when typing gcc -v and g++ -v i get;

[ns219a@localhost ns-allinone-2.1b9a]$ gcc -v Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs

and

but when i try to compile the application it looks like it is sing gcc4.1 as you can see from teh error;

the application is a free source netwrok simulator. the version i am installing is a bit outdated but it is the only one that has an ATM module and wont install without gcc32. i have already modified some of the c++ code to resolve some compatibility issues but this one beats me.

any help would be much apreciated.

Maybe the c++ command is a link which points to g++ version 4.1.1. If this is the case, just remove the link and recreate it to point to g++ version 3.2.3. Or eventually, before compiling set the environment variable CC using the full path to gcc version 3.2.3 and CXX to the full path of g++ version 3.2.3.

Firstly, Thank you for the prompt response.

This is exactly what i am doing just in case the command i am using is ./install CC=/usr/bin/gcc32;CXX=/usr/bin/g++32

i will try to locate the c++ comand and see where it is pointing to.

MonderS · 02-03-2009, 03:21 PM

Hi colucix,

the c++ is a binarry running from the usr dir;

[root@localhost ns-2.1b9a]# which c++
/usr/bin/c++

i cant find any hardcoded paths that refer to gcc 4 in the make file but one thing pups out, its the gcc lib directory. the compat-gcc32 installed its minimal lib on /usr/lib/gcc-lib while the original gcc had it on /usr/lib/gcc. simply changing the gcc-lib to gcc breaks everything which tells me that the gcc32 libs are very minimal.

as you can see both libraries have;

any ideas? this is all new to me and i am trying to give you as much info as i can but i am most likely going to miss sone important info. please let me know if you need any other info.

This does not tell you that c++ is a binary. Try the following commands to be sure:

Code:

$ ls -l /usr/bin/c++
$ file /usr/bin/c++
$ rpm -qf /usr/bin/c++

Also, please post the output of

Code:

$ /sbin/ldconfig -p | grep gcc

this will print out the content of the library cache. I'd like to know if the cache has been updated by including the newly installed libraries.

colucix · 02-03-2009, 08:05 PM

Ok, thanks. I think that the problem is still to tell the installation program to use a compiler different from c++. In one of your previous posts you talked about this command:

Code:

# ./install CC=/usr/bin/gcc32;CXX=/usr/bin/g++32

if you really put a semi-colon between the two variable assignments it does not work (the second assignment is done on a different command). But I wonder if the install program is able to see the environment variables CC and CXX. After checking this by looking inside the install script, you can try the following three-liner alternative:

Code:

# export CC=/usr/bin/gcc32
# export CXX=/usr/bin/g++32
# ./install

MonderS · 02-04-2009, 04:42 PM

Hi colucix,

I did follow the instructions provided setting the variables for CC and CXX before calling the install script but this made no difference. Also, i cant seem to find any reference to CC and CXX in the install script.

I totally agree that the main issue here is forcing the application to use the g++32 compiler which i dont think it is doing now or at least if it is doing it is not pointing to the correct lib directory as you can see from the error where the path points to /usr/lib/gcc rather than /usr/lib/gcc-lib which is related to the gcc32.

i was thinking of installing the full 3.2 version rather then the minimal compat but i am not sure this will 1) install on rh5, 2) resolve the issue since i am not sure how the c++ is being called. the package can be downloaded from http://www.isi.edu/nsnam/dist/ns-all...a-gcc32.tar.gz

looking forward to hear your intake on this.

Thanks for all your help so far.

Indeed, it is still using the 4.1.1 version since you saw that c++ has been installed by gcc-c++-4.1.1-52.el5. I looked at the installation program in the package you linked. It is a simple wrapper which in turn goes into subdirectories and executes ./configure and make command from there. The usage of c++ is set when each ./configure is called.

At this point, the most straightforward thing to do is:
1) rename the c++ executable to safely keep a backup copy of it, e.g.

Code:

cp -p /usr/bin/c++ /usr/bin/c++.original

2) create a link in /usr/bin pointing at the g++ executable installed by the 3.2 version, e.g.

Code:

cd /usr/bin
ln -s /usr/bin/g++32 c++

3) Run the installer again still exporting at least the CC variable before it

Code:

CC=/usr/bin/gcc32
./install

4) Good luck!

Ciao colucix,

I am now passing the previouse break point but i get this error;

diffusion3/lib/dr.o: In function `std::list<DiffusionIO*, std::allocator<DiffusionIO*> >::_M_insert(std::_List_iterator<DiffusionIO*>, DiffusionIO* const&)':

Compile the old version of gcc and install it into its' own prefix like /usr/gcc323. Then create a wrapper script which sets the path to the bin dir under the new prefix -something like this

#!/bin/bash
export PATH=/usr/gcc323/bin:$PATH
exec $@

This is the way I compile and install extra compilers. Some folks would recommend you to compile using the normal prefix, but using --program-suffix=-323 and then trying to set the CC and CXX env variables as you are trying to do. But, you'll have the same problem if the Makefile (or whatever) is hard-coded to call gcc or g++. Putting everything in an alternate path makes it more dependable and easier. Using the the above wrapper (named GCC323 and placed in your path) then you'd just run:
GCC323 ./install

The other thing you could do would be to inspect the install script and see how it is doing that -it may have hard-coded full paths. if so, simply edit to point to your alternate compiler.

MonderS · 02-05-2009, 01:43 PM

gnashley,

I am not sure i follow? a compat-gcc32 is already installed and if you read colucix entries he already established where the gcc4 is being referenced. i am not sure installing gcc32 again would make any difference as gcc -v returns the desired version but the c++ used to refer to 4.1 but not any longer since i mad the changes colucix advised me to make. the only problem i am having now is to do with the
std::_List_node_base::hook(std::_List_node_base*)'
collect2: ld returned 1 exit status

please let me know if i missunderstod your entry. also, please note that i already tried to compile the gcc32 full version to no avail and the rpm will fail since there is a known bug in intalling the full gcc32 version on rhl5.

Regards,
Monder

gnashley · 02-05-2009, 01:51 PM

Sorry, I didn't see the last post -I was doing some other things and had not refreshed the page before finally posting.
Still, my bit of advice is good if you ever find yourself needing to have multiple compilers co-exist in a sane way.

MonderS · 02-05-2009, 02:04 PM

Thanks for the advise anyway. any one who takes time to help a fellow in need deserves all my respect and gratitude
