Can't target 32 bit compile on a 64 bit machine (-m32) #35

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. On a 64 bit linux install. Try to compile the code so it can run on
   a 32 bit machines. Run config with ./configure CFLAGS=-m32
2. make
3.

What is the expected output? What do you see instead?

I am expecting the library to compile fine. It does when I do not use the
CFLAGS=-m32. What I get instead is :

src/signalhandler.cc: In function `void* google::<unnamed>::GetPC(void*):
src/signalhandler.cc:72: error: `REG_EIP` was not declared in this scope
 src/signalhandler.cc:72: warning unused variable `REG_EIP`

What version of the product are you using? On what operating system?

glog v0.2.1/v0.3.0 

os : RHE4.0x64

Please provide any additional information below.

Thanks !

I have the same problem attempting to compile code with gflags under Ubuntu 
9.10 
64bit.  It seems to happen with or without "CFLAGS=-m32" Any assistance would 
be 
appreciated. Thank you!

I guess you need both CFLAGS=-m32 and CXXFLAGS=-m32 ?
