FetchFileJob.cpp does not cross-compile on Ubuntu 14.04

[starsseed]

in ubuntu 14.04 libcurl4-openssl-dev, /usr/include/curl/curlbuild.h is different for x86 and X86_64

CURL_SIZEOF_LONG and CURL_SIZEOF_CURL_OFF_T are set to 4 for x86 and 8 for x86_64

Similar to #10806. The bug is in Ubuntu and you should be able to easily work around by not forcing a 32-bit build.

I don't understand what you mean by "you should be able to easily work around by not forcing a 32-bit build" : Haiku *is* 32bit (and I'm not forcing anything : I just try to compile a standard gcc2-hybrid)

the problem is that the Haiku build system try to compile things with linux's headers instead of it's own.

So far you failed to write how you do that, particularly what arguments you pass to configure.

No, that is not a problem. There are tools we build for the host platform, so we need to use the host platform's headers. You haven't even provided sufficient information on what fails exactly (if you don't know what you're doing, please always attach a complete build log), but I'm fairly confident that in this case compiling FetchFileJob.cpp fails for libpackage_build.

It currently works fine on the Mint LMDE (Debian testing) x86_64 buildslaves, so either you're doing something wrong, or Ubuntu has something difference from Debian and mint.

[jackburton]

I have the same problem on Ubuntu 14.04, so either starsseed is not doing anything wrong, or we are both doing it :-)

[jackburton]

Well, I didn't read the ticket correctly. Here it simply fails not finding curl.h, although it's there:

stefano@Mazinga:~$ dpkg -L libcurl4-openssl-dev | grep curl.h /usr/include/curl/curl.h

Note that there is no /home/stefano/haiku/haiku/generated/build_packages/curl_x86-7.45.0-2-x86_gcc2/develop/headers/x86 directory. IOW: no libcurl headers in the cross compile directories.

[jackburton]

More investigation:

Previous curl packages had the develop directory:

stefano@Mazinga:~/haiku/haiku$ ls generated/build_packages/curl_x86-7.44.0-1-x86_gcc2/ bin data develop documentation lib

stefano@Mazinga:~/haiku/haiku$ ls generated/build_packages/curl_x86-7.43.0-1-x86_gcc2/ bin data develop documentation lib

Current curl package doesn't have it: stefano@Mazinga:~/haiku/haiku$ ls generated/build_packages/curl_x86-7.45.0-2-x86_gcc2/ data lib

When you are compiling the building-tools for haiku (and not Haiku itself), you have to target your building platform (here, ubuntu)

If you have a 64bit Ubuntu and a 32bit GCC, you have to switch to a 64 bits GCC (no matter you want to compile haiku in 32-bit or in 64-bit.)

It fixed the build for me.

So, do I have to specify some extra options on the "configure" commandline ? I did not target any specific platform and just leaved the default.

If you have a 64bit Ubuntu and a 32bit GCC, you have to switch to a 64 bits GCC (no matter you want to compile haiku in 32-bit or in 64-bit.)

You mean for the cross-compiler ? How do I check if the cross-compiler is 32 or 64 bit?

[starsseed]

Replying to jackburton:

just check the installed packages from your package manager then, uninstall all gcc32 packages and (re)install standard GCC (or better: upgrade to 16.04 / just to feed the troll ;-) )

So, do I have to specify some extra options on the "configure" commandline ? I did not target any specific platform and just leaved the default.

(iirc) leave the default, Ubuntu will use the default compiler, however, don't forget to clean EVERYthing before.

@jackburton: your issue is different, since it is failing during build of the "target" version of the file. What could have happened is that download or extraction of the curl_devel package failed. Try deleting the generated/downloads and generated/build_packages dirs and running your build again (while connected to internet so the downloads can be done).

That worked. For some reason I was sure I had already tried that. Thanks!
