QNX IDE compile error when cygwin window open on my machine   
I am running QNX Momementics 4.6.0 from the QNX 6.4.1 software development suite.

I am compiling the code on a Windows XP machine.

An ARM BSP fails to compile when I have a cygwin shell open (cygwin is already installed on this machine and used for 
other purposes).  The CC1 compile that comes with QNX fails to find files due to some sort of conflict with an open 
cygwin window.  As soon as I exit the cygwin shell I am able to compile in QNX again.

Any ideas how to fix this incompatibility?

Re: QNX IDE compile error when cygwin window open on my machine   
Hi, Scott,

Can you be more specific about the nature of this conflict between cc1 
and cygwin?  It is my understanding that cc1 is not a cygwin executable; 
it's "pure Windows."

What error messages are you seeing on the console?

How many versions of cygwin do you have installed?  Are you perchance 
using the cygwin environment that is bundled with the Photon 
AppBuilder?  I ask because this only seems likely if you are attempting 
to load multiple versions of the cygwin DLL, which could conflict.  
Other users report no problems using cygwin with this and SDP release.

Cheers,

Christian

RE: QNX IDE compile error when cygwin window open on my machine   
Hi Christian,

Please see the compile errors below.  Using cygcheck, it looks like I am using cygwin 1.5.25-15.
If I close the cygwin shell, the compile works fine.  If I have a cygwin shell open the QNX tools fail to compile.

Hi Christian,

Any word on how to make QNX not conflict with existing cygwin installed on my PC?

 Scott

Hi Scott,

Can you post the full build logs (i.e. stdout/stderr) for both the 
failing and successful build?

RE: QNX IDE compile error when cygwin window open on my machine   
Where are the full build logs located in a QNX build?  The only log I have is the console log?

The console logs will do. If you're building from the command line, 
redirect stdout and stderr to a file.

Re: QNX IDE compile error when cygwin window open on my machine   
Build log attached.  find.exe fails because there are 2 different versions of cygwin1.dll on the machine.  One is in c:\
cygwin\bin and the other is in c:\qnx641\host\win32\x86\usr\photon\bin.

I think the problem is that QNX should use another dll name rather than cygwin1.dll.  That way it will not pick up other
 (standard) cygwin installations on the machine.  The strange thing is QNX runs fine until the standard cygwin shell is 
opened...

It only happens when you have the the cygwin shell open because its 
tries loading conflicting dlls. You can avoid this by copying your more 
recent C:/cygwin/bin/cygwin1.dll into %QNX_HOST%\usr\photon\bin which 
should fix the problem with find.exe.

Re: QNX IDE compile error when cygwin window open on my machine   
Replacing cygwin1.dll in C:\qnx641 with the one found in C:\cygwin\bin solves the problem.  This will make life a lot 
easier to develop with the QNX tools.  Thank you!
