[CMake] Problem with Ninja on Windows

2017-04-24 Thread Robert Bielik 
Hi all,

I've come to a problem with Ninja on Windows, but only when building for MSVC 
amd64 toolchain. With x86, it works OK. The error I get is:

CMake Error: Error required internal CMake variable not set, cmake may be not 
be built correctly.
Missing variable is:
CMAKE_ASM_NASM_COMPILE_OBJECT

It is boringssl (from the gRPC project) that needs NASM. But I find it odd that 
the x86 generator works, but not the amd64 one ?

Any ideas what I should look for ?

Regards
/Robert

Re: [CMake] Problem with Ninja on Windows

2017-04-24 Thread Robert Bielik 
I've found the culprit, in boringssl/crypto CMakeLists.txt there is:

enable_language(ASM_NASM)

If I remove this (since I don't use asm), it works on both x86 and amd64 (!)

What compiler are you using (what does CMake say it is?)? Does an
`strace` of CMake configuring the project show anything interesting?
`cmake --trace-expand`?

Re: [CMake] Trouble with FindPNG module

2017-04-24 Thread Andrew Fuller 
Where did the library get installed on your system?  What's the value of 
CMAKE__LIBRARY_ARCHITECTURE?


Since you're on a 64-bit system, I'd expect CMake to be looking for 64-bit 
libraries unless you've told it otherwise.

It's using Gcc 4.9 because I told it to via toolchain file:



-- The C compiler identification is GNU 4.9.4
-- The CXX compiler identification is GNU 4.9.4
-- Check for working C compiler: /usr/bin/gcc-4.9
-- Check for working C compiler: /usr/bin/gcc-4.9 -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
-- Detecting C compile features
-- Detecting C compile features - done
-- Check for working CXX compiler: /usr/bin/g++-4.9
-- Check for working CXX compiler: /usr/bin/g++-4.9 -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done



Via the following toolchain file contents:



set( CMAKE_SYSTEM_NAME Linux )
set( CMAKE_SYSTEM_VERSION 1 )
set( CMAKE_SYSTEM_PROCESSOR "i686" )
set( CMAKE_C_COMPILER gcc-4.9 )
set( CMAKE_CXX_COMPILER g++-4.9 )
set( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -m32" )
set( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -m32" )



I'm not sure how to use strace. I tried following instructions I found
on the [CMake Performance Tips][1] page, but this isn't working. My
generate command has a lot of options, so I use a helper shell script
to generate. strace seems to not work well when using a shell script.
Trace also doesn't show much useful. Could you give exact command line
I can run to get the info you need?

Where possible, I install everything via apt-get for the 4.9
toolchain. For libpng this was not an option as far as I could tell,
so I'm not sure what implications that has on find_package() behavior.

Re: [CMake] Trouble with FindPNG module

2017-04-24 Thread Robert Dailey 
Interestingly, the changes to my toolchain made below work:


set( CMAKE_SYSTEM_NAME Linux )
set( CMAKE_SYSTEM_VERSION 1 )
set( CMAKE_SYSTEM_PROCESSOR i386 )
set( CMAKE_C_COMPILER gcc-4.9 )
set( CMAKE_CXX_COMPILER g++-4.9 )
set( CMAKE_C_COMPILER_ARG1 -m32 )
set( CMAKE_CXX_COMPILER_ARG1 -m32 )


The only change here is that I'm using CMAKE_C_COMPILER_ARG1 and
CMAKE_CXX_COMPILER_ARG1. These are not documented anywhere. I only
found out about them from a post from Bill Hoffman (which I have lost
the URL to).

Is this the correct toolchain? At least find_package() is properly
finding 32-bit libraries now, so I am happy. Should
CMAKE_SYSTEM_PROCESSOR be i386 or i686?

Try adding this to your toolchain file:

Does the information in the CMakeFiles/$cmake_version directory contain
anything indicating that it's detecting the compiler as 64-bit?

Sorry, it's such a common tool I use, I forget others are new to it :) .
Here's how I'd use it to debug this:

strace -s 1 -e file -o cmake.strace.log $cmake_command

If your cmake command is a script that later launches CMake, you can
give strace `-f` to have it also trace any child processes made by the
command. In the resulting log file, you'll see syscalls CMake is making.
searching for the png header/library searching area shouldn't be too
hard. Is it looking in anything resembling the right paths?

[CMake] Building with cmake 3.6.2 need 3.7.2 or newer!!

2017-04-24 Thread Chris Russo 

Greetings-

Well this should be simple right? I have Windows 10 64 bit. Visual 
Studio Community 2015. It shows that my version on a certain build is 
cmake 3.6.2. I have tried to download the latest and greatest set the 
path and no luck.


where is, which, find, search looking all over the file system I cannot 
find cmake 3.6.2 at all. I am trying to figure out what application 
actually installed cmake 3.6.2 and I cannot figure it out. I haven't 
looked into regedit.exe because I just thought I should reach out to the 
experts on this issue.



So the real question here is. Maybe I don't really care about where 
cmake 3.6.2 lives. I would just like to upgrade to 3.7.2 or later. Set 
the path as the installer does and use Git Bash shell to invoke cmake 
3.7.2 or greater.


Could you please tell me my simplest option. I hope my cmake isn't on 
your system. If you know what I mean. LOL!!


Thanks in advance. Any help would be greatly appreciated. If you want to 
see where is, or which from Git Bash Shell I will be mre than happy to 
provide it.



Regards-


Chris Russo
