CodeLite IDE

Howdy. Running codelite 6.1 on my 64 bit linux wheezy system. Need to create the app to run on a 32 bit system but cannot find anywhere in the ide how to set the -m32 g++ compiler switch. Any suggestions?

Hi,
There are number of ways of achieving this, I will name some:
1. Open the project settings dialog -> common settings-> compiler and simply add "-m32" to the "compiler options" field
2. You can create a new compiler with this flag enabled:

* settings->build settings->compilers->add compilers->clone an existing compiler
* give the compiler a name + select the compiler to clone
* after the new compilers is added to the list of compilers, click it and select the "Tools" tab (the first tab on the left)
* in the "C compiler" and "C++ compilers" field simply append -m32 to the tool path

Outstanding, eranif, your method #1 worked great. Thank you.

This is a simple console application.

When I build from the command line using
g++ main.cpp -Wall -m32 -o interleave
everything works fine.

When I just compile the source from within codelite with the -m32 flag there are no errors.

However when I try to build with codelite I get a ton of errors.

My build window is:

/bin/sh -c '/usr/bin/make -j2 -e -f Makefile'

It builds just fine without the -m32 flag.

Here's some of the code:
typedef struct {
string FolderName;
vector<string> FilesInThisFolder;
} ThisMusicFolder;
string AMusicFile;
vector<string> AllMusicFiles;

string FolderName;

vector<ThisMusicFolder *> AllMusicFolders;
vector<ThisMusicFolder *>::iterator PointerToLargestFolderInAllMusicFolders;
vector<ThisMusicFolder *>::iterator Pos;
vector<ThisMusicFolder *>::iterator allPos;

vector<string>::iterator strPos;
vector<string>::iterator filesPos;

int endoffoldername;

endoffoldername = AMusicFile.find("/",0); //main.cpp:107
if (endoffoldername == -1) {
continue;
}


My codelite, now version 7.0, came from the debian linux repository.
Any ideas?

Its not really related to codelite. You need to search your linker man page to see if you are missing some flags

Hi,

Don't you need to pass -m32 to the linker too?

Thank you DaviGH, you were exactly right. I was thrown off by the fact that the cli build worked without having to say anything to the linker, just g++ ... -m32.
