I tried to build WebKit GTK on my ARM Mac, but the linking process fails:

I'm not sure why this is happening. It compiled just fine on my Intel Mac. Any ideas on how to fix this?

I'm getting the following linker errors...

when using g++ to link, I am passing -lIlmImf-2_5, I've checked this file with `nm' and it seems to have the symbols that the linker is looking for.

Edit: I now understand that the order of the libs matters, thanks n-1-8e9. However I still have some problems I can't sort out.

How do I fix it?
While tracing a bug in a static library we use in our iOS application I stumbled upon the following question:
The library we use has code that is automatically executed during the launch of our application, before our application's main method is executed. The stack trace while the function is executed looks as follows:
#0 0x000000010050ce04 in _runOnLoad ()
#1 0x000000012008ceb0 in ImageLoaderMachO::doModInitFunctions(ImageLoader::LinkContext const&) ()
#2 0x000000012008d050 in ImageLoaderMachO::doInitialization(ImageLoader::LinkContext const&) ()
#3 0x0000000120088808 in ImageLoader::recursiveInitialization(ImageLoader::LinkContext const&, unsigned int, char const*, ImageLoader::InitializerTimingList&, ImageLoader::UninitedUpwards&) ()
#4 0x00000001200879b0 in ImageLoader::processInitializers(ImageLoader::LinkContext const&, unsigned int, ImageLoader::InitializerTimingList&, ImageLoader::UninitedUpwards&) ()
#5 0x0000000120087a64 in ImageLoader::runInitializers(ImageLoader::LinkContext const&, ImageLoader::InitializerTimingList&) ()
#6 0x000000012007a08c in dyld::initializeMainExecutable() ()
#7 0x000000012007e0fc in dyld::_main(macho_header const*, unsigned long, int, char const**, char const**, char const**, unsigned long*) ()
#8 0x0000000120079044 in _dyld_start ()
My question is: What is going on here?
How does the image loader know that this method should be executed? When looking at the assembler of the static library, _runOnLoad() looks like a regular method. How is the information that this method should be executed on launch stored in the static library? Where is this information stored when the library is linked to our main application?
How can you specify this when compiling? Can you flag a method to be executed on load? It this something you do in code or is it a compiler argument?
While this method is run, what can I do? I assume other functions and classes are not guaranteed to be loaded yet?
This whole thing is happening inside an iOS application, but this seems to me to be very low level functionality, so I assume this works on every unix based platform?
I would love to learn some more about this.
I met the following error while compiling z3. It seems to be an error for ld. I wonder what I can do to make it compile. It is a problem from the opt branch in git. I am on iMac with OS X 10.9.2 (13C1021)
I am with xcode Version 5.1.1 (5B1008) with xcode-select tools installed to version 2333. I use port with version 2.2.1 with ld installed.
The problem seems to be a linking problem. I am using link loader as: ld64 #136_2+llvm33 (active)
My gcc is gcc (MacPorts gcc48 4.8.2_0) 4.8.2
Thank you very much!

It is because we used port and installed gcc and ld and other packages.
Another possibility is that ld was depend on llvm 3.3 rather than llvm 3.4. The problem was solved after updating ld.
I'm developing software that uses DB2 database via ODBC (unixodbc). The issue is that running test suite with valgrind produces massive amount of errors. Let alone one connect and disconnect generates 4k error messages (code provided below). My question is:
Am I doing something wrong with connect and disconnect?
Is there clean up function that frees allocated memory by libdb2?
Valgrind also has message suppression feature, is there maintained suppression file for libdb2.so library?
Code:
static void
connect_disconnect(SQLCHAR *dsn)
{
SQLRETURN ret = -1;
SQLHENV env = NULL;
SQLHDBC dbc = NULL;
SQLCHAR msg[1024];
SQLSMALLINT msglen = 0;
/* env handle */
SQLAllocHandle(SQL_HANDLE_ENV, SQL_NULL_HANDLE, &env);
SQLSetEnvAttr(env, SQL_ATTR_ODBC_VERSION, (void*)SQL_OV_ODBC3, 0);
/* connection */
SQLAllocHandle(SQL_HANDLE_DBC, env, &dbc);
ret = SQLDriverConnect(dbc, NULL, (SQLCHAR *)dsn,
SQL_NTS, msg, sizeof(msg), &msglen, SQL_DRIVER_COMPLETE);
if (!SQL_SUCCEEDED(ret))
{
fprintf(stderr, "Failed to connect to database '%s'.\n", dsn);
extract_error(dbc, SQL_HANDLE_DBC);
}
SQLDisconnect(dbc);
SQLFreeHandle(SQL_HANDLE_DBC, dbc);
dbc = NULL;
SQLFreeHandle(SQL_HANDLE_ENV, env);
env = NULL;
return;
}
I'm using:
libdb2.so acquired from DSClients-linuxx64-odbc_cli-10.1.0.2-FP002 package for Linux 64bit.
libodbc.so version 2.3.1

Most of leaks are static (initialization). Each connect disconnect adds 80bytes to definitely lost byte count.
A bit bigger part of valgrind output (could not paste more then 500k): http://pastebin.com/xZfjy21Q
Biggest issue is that I cant find issues caused by my actions.
Edit
Double checked binaries, all are 64bit.

Can someone help? I manually installed
latest version of BLAS
lapack-3.4.0
boost-1.48.0
latest version of ATLAS
I'm using Ubuntu 11.04 on the MacBook Pro 7,1 model
Thank you so much to osgx! After reading his comment, I took a second look at the README file! It turns out I was missing '-O1 -larmadillo' in the command!
Here's the command I used to get it working:
g++ example1.cpp -o example1 -O1 -larmadillo
Stupid mistake, I know.... It just goes to remind you how important it is to read the README.
The README also mentions:
If you get linking errors, or if Armadillo was installed manually
and you specified that LAPACK and BLAS are available, you will
need to explicitly link with LAPACK and BLAS (or their equivalents),
for example:
g++ example1.cpp -o example1 -O1 -llapack -lblas
I didn't have to include '-llapack -lblas' but maybe this will help anyone else who's having similar problems.
As of 5.0.0 (might also apply to earlier versions)
You actually need -larmadillo, on Fedora 21 -llapack and -lopenblas are not excplicitly necessary anymore.
There's an oddity I just discovered by comparing previously working compilations of code with the very problem of this thread, stressing the involvement of the gnu cc (I'm no expert in this): on my machine compilation success depends on the order of parameters to the gcc/g++ where
g++ infile -o outfile -libarmadillo ... worked, but
g++ -libarmadillo infile -o outfile ... didnt with (almost) the same error as mentioned above.
(hope that helps).
