compiling error: "touch: cannot touch ..."

[jondiced]

Hey everybody,

I'm trying to compile a program but I'm getting an error that's driving me bonkers. I've posted the entire output from make, but the part with the error is here:

touch: cannot touch `/home/aguilar/geant4/LumiCal-pro/tmp/Linux-g++/Lcal-pro/exe/obj.last': No such file or directory
make: *** [/home/aguilar/geant4/LumiCal-pro/tmp/Linux-g++/Lcal-pro/exe/obj.last] Error 1

The idea is that I'm using a toolkit called Geant4 to write a program that does some particle physics simulation. My program needs to have the proper environment to access the Geant4 libraries, as well as some other libraries. Could this be the source of the problem?

Thanks for your help,

jondiced (who is becoming quite actually jaundiced by this problem!)

Does the

/home/aguilar/geant4/LumiCal-pro/tmp/Linux-g++/Lcal-pro/exe/

directory exist? Do you have permission to write on it?

[MadCow108]

I once had a similar problem when compiling root.
It couldn't touch a file although the directory existed and permissions where ok.
I just touched the file by hand and it worked with no problems.
no idea what caused it.

[jondiced]

Permissions are OK. The directory doesn't exist but make should create it. When I try making the directory and file by hand, I get an "undefined reference to main" error:

Using granular libraries ...
Linking Lcal-pro ...
/usr/lib/gcc/i386-redhat-linux/3.4.6/../../../crt1.o(.text+0x18): In function `_start':

collect2: ld returned 1 exit status
make: *** [/home/aguilar/ilcsoft/v01-06/Mokka/mokka-06-07-patch02/bin/Linux-g++/Lcal-pro] Error 1

Unfortunately, Googling for the error just returns thousands of people's unrelated errors where "touch: cannot touch" happens to turn up!

[jondiced]

Problem solved! Solution here, which I can't believe I didn't find earlier: http://hypernews.slac.stanford.edu/H...html?inline=-1

Anyway, the following 3 items must be the same:
1. Executable name in the makefile
2. Directory name
3. Foo.cc (replace "Foo" with executable name)

Thanks for your suggestions. Hope this helps anyone else in the future.

OMG that is sooooo frustrating. It took me like half an hour of debugging to find the difference between Nozzel01 and Nozzle01. Thanks though .
