[LLVMdev] Build problems and workarounds with CMake and XCode

[Samuel Crow]

Hello everyone,

I finally gave up on trying to build under Eclipse on my Mac because I had a 
non-functioning installation on there that kept intercepting the command line 
entries on the path.  Uninstalling the old MacPorts install of LLVM 2.6 helped 
but not completely.

I tried making a separate build of LLVM SVN in XCode using build files created 
with CMake.  Surprisingly, it worked better than Eclipse!  The Build_All target 
completed its build.  The install target was another story though.  First of 
all, the commands to install with the terminal command-line needed to be 
prefaced with sudo to work.  Secondly, those commands, when executed from XCode, 
have no open console to prompt for a password.

My workaround for that was to write a small utility in Qt to prompt for a 
password and return it in stdout.  I then set the path of that utility to the 
SUDO_ASKPASS environment variable so I could set the scripts to run sudo -A 
command instead of sudo command.  This unearthed a second problem.  In my debug 
build, the script looked in the release directory for LLVMSupport.a and failed 
as a result of it.

At this point I'm building a release build so I can install the debug build. 
 If Óscar or somebody more familiar than I at CMake would look into the issue of 
the release install in the debug build, I'd appreciate it.  Secondly, if anyone 
would be interested in my password prompter software, I'd be interested in 
releasing it as open-source.

Thanks for your time and efforts,
