RE: Cmake on cygwin64 fails with error "C compiler "/usr/bin/cc" is not able to compile a simple test program"
I rebooted my PC in Safe Mode and everything works fine on the same PC with the same cygwin64 installation. CMake is OK in Safe Mode. Some other processes that run during regular boot must be interfering with CMake. Definitely BLODA. I never even heard that term before yesterday, and look at me now. If I ever figure out specifically what is interfering I'll post it. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

The attached zip file contains the results when I create a directory called cmaketest64, put the two files from my previous post (CMakeLists.txt and tutorial.cxx) in it, and type "cmake ." I had to change the file extension from .zip to .z__ and remove two .exe files to get past the spam filters: cmaketest64/CMakeFiles/3.3.2/CompilerIdC/a.exe cmaketest64/CMakeFiles/3.3.2/CompilerIdCXX/a.exe cmaketest64.z__ Description: cmaketest64.z__ -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

I made the world's smallest example, taken from the CMake tutorial.
There's a CMakeLists.txt that contains this:
cmake_minimum_required (VERSION 2.6)
project (Tutorial)
add_executable(Tutorial tutorial.cxx)
and a tutorial.cxx that contains this:
// A simple program that computes the square root of a number
#include
#include
#include
int main (int argc, char *argv[])
{
if (argc < 2)
{
fprintf(stdout,"Usage: %s number\n",argv[0]);
return 1;
}
double inputValue = atof(argv[1]);
double outputValue = sqrt(inputValue);
fprintf(stdout,"The square root of %g is %g\n",
inputValue, outputValue);
return 0;
}
Just create the two files above and do:
$ cmake .
$ make
$ ./Tutorial 2
On 32-bit Cygwin, it all works nicely as expected. But on my fresh 64-bit
installation, I get the " not able to compile a simple test program" message.
I think Hans-Bernhard's theory that there's some other app interfering is
probably correct, and it probably has something to do with my company's
security software.
I will post more information in subsequent posts that hopefully stay under
the "spam score threshold".

This would explain why I'm having the same bad behavior on multiple PC's at work--they all have the same BLODA. But it's strange that 32-bit works and 64-bit doesn't, and that an older version of 64-bit Cygwin worked. I will try from my home PC to see what happens. I am also trying to send a message with a more complete package of the errors, but so far the mail server on one end or the other has rejected my attempts. Will keep trying. -- Frank -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple

Well, FWIW, with the CMake-based projects I've been building here (Windows10 64-bit, Cygwin 64-bit, packages gcc 5.4.0-1, cmake 3.3.2-1, GNU make 4.2.1-1), it has worked just fine, and still does. I've built the current upstream release version of cmake itself with it, among quite a number of things.
