Configure Error

Hi,

I am trying to cross compile Mono for an ARM target (XScale Intel PXA255). While cross compiling my ./configure breaks, I am pasting the last few lines of the error below.

Can anyone please let me know why is this happening.

Thanks.

Your make file is wanting to run some type of test suite but it can't because the generated code is Arm not x86. Try "make help" to try and get a list of targets, if that doesn't work try "make mono" and it that doesn't work then create a pastebin of the makefile and post the link so I can look at it.

Thanks for replying..

But it isnt the make which I am stuck at.. I have still not reached the Make part yet.. I am stuck at ./configure itself.. I could also understand that it is trying to run some test suite but I am not sure if there was any way to make it stop testing it.. please advice..

During the ./configure there is probably an option like --no-testsuite that could be entered to avoid this. Post the results of "./configure --help" as you seem to not understand that sometimes during configuration code is compiled and ran as a test to make sure your environment is ready to compile the project.

Hi,

I tried but it does not seem to be a valid option.

The ./configure -h output,

Please let me know if you find what the issue is. Many thanks.

Something is wrong with your -I or include path and I think you need to add --with-glib=embedded and maybe --disable-shared to your ./configure

What are you trying to get from mono, just moonlight?

I tried adding those to variables, it again did not work. It is stuck at the same place. Any ideas as to what could be wrong with -I.

I don't need Mono for Moonlight, I need the complete set of libraries and compilers because I need to run a C# based application on a device.

Actually I could compile the mono inside a scratchbox but the linux version in my device is 2.4 and the binaries were compiled for version 2.6. Later I realised by posting in LQ that Mono is not kernel dependent and the problem is because of glibc incompatibility. I want to compile mono with glibc version 2.2.5 (that is what my device has) but scratchbox only supports toolchain from glibc version 2.3 and above. So I am stuck here, is there any work around for this?

I'm limited to my blackberry so I can't really help much more with such a complex project without downloading and checking it out first. You must have quite the capable Arm device to be running mono on it, all my stuff if MIPS32 which also hinders my knowledge of the compiler toolchain your using. I want to help you I just don't see how without having the source and toolchain your using....I know how frustrating it is to cross compile complex projects. I think I would post this question in the mono forum if they have one also.

What I was saying about -I is that I see in the pastebin that configure can't find some source files, so you need to find the files that are referenced by an error of not found and add the directory containing the files to your includes.

Your work around is to build the needed glibc version with your cross compiler and build mono against it.

Thanks for the concern, it indeed is frustrating.

Actually the toolchain which I am using as of now has the required glibc version and I know the fact that anything compiled using this toolchain runs on my device.

Please let me know if you get any inputs from other forums as well. If you need the toolchain I can send it to you. Besides that I am just compiling the Mono 2.0 source with the compiler in my tool chain.

Thanks again.

I don't need the toolchain thanks, so now you have what you need your back to configuration again yes?

Yes, I do have the necessary toolchain but I am not sure how to fix this error and move to the next step.

Did anyone fixed this error yet?
