 Posted: Thu Jul 11, 2013 3:40 pm Post subject: crossdev with MinGW : cross emerge claims existing simlinks |
 |
|
Hi all,
I need to set up a cross compiler environment with MinGW for building and testing my application. I have followed :
| Code: | emerge -av crossdev
# switched /etc/portage/package.* to directories
# added "/usr/local/portage/cross-i686-pc-mingw32" into PORTDIR_OVERLAY
crossdev --ov-output /usr/local/portage -t i686-pc-mingw32
emerge-wrapper --init |
| Code: | # ls -l /usr/i686-pc-mingw32/etc/make.profile
lrwxrwxrwx 1 root root 30 11 juil. 12:08 /usr/i686-pc-mingw32/etc/make.profile -> /usr/portage/profiles/embedded |
The cross compiler looks working :
| Code: | $ cd test
$ echo 'int main(){return 0;}' > test.c
$ i686-pc-mingw32-gcc -Wall test.c -o test
$ file test
test: PE32 executable (console) Intel 80386 (stripped to external PDB), for MS Windows
$ wine test.exe |
But when I try to cross-emerge, I have the following error : | Code: | # i686-pc-mingw32-emerge net-libs/zeromq
!!! /usr/i686-pc-mingw32/etc/make.profile is not a symlink and will probably prevent most merges.
!!! It should point into a profile within /usr/portage/profiles/
!!! (You can safely ignore this message when syncing. It's harmless.)

I have added : | Code: | ln -s /usr/portage/profiles/embedded /usr/i686-pc-mingw32/etc/portage/make.profile
mkdir /usr/i686-pc-mingw32/usr/portage
/usr/i686-pc-mingw32/usr/portage/distfiles
i686-pc-mingw32-emerge --sync |
But when I try to emerge something : | Code: | # i686-pc-mingw32-emerge app-portage/eix
!!! /usr/i686-pc-mingw32/etc/portage/make.profile is not a symlink and will probably prevent most merges.
!!! It should point into a profile within /usr/portage/profiles/
!!! (You can safely ignore this message when syncing. It's harmless.)

I have defined the simlink as requested (cf 1st line). So ? |

| It looks like you synced into the wrong directory. However, there was no need for you to sync a second copy of the tree at all. In most cases, you want /usr/sysroot/usr/portage to link to /usr/portage. |

I'm having a similar issue, but with arm. I set up a link from /usr/armv5te-softfloat-linux-gnueabi/usr/portage to /usr/portage, but I'm still getting the ARCH error.
| Code: |
jrsmith3@gentoo ~ $ ls -l /usr/armv5te-softfloat-linux-gnueabi/usr/

@Hu : Thanks for the tip. I have deleted /usr/i686-pc-mingw32/usr/portage and made a link instead to /usr/portage.
For the rest, the problem remains the same : | Code: | # i686-pc-mingw32-emerge app-portage/eix
!!! /usr/i686-pc-mingw32/etc/portage/make.profile is not a symlink and will probably prevent most merges.
!!! It should point into a profile within /usr/portage/profiles/
!!! (You can safely ignore this message when syncing. It's harmless.)

One solution to:
I add to /usr/portage/profiles/embedded/make.defaults:
ARCH="x86"
But I'm not sure, maybe requires: x86-winnt
-------------- On russian ------------------
Одно из решений:
Я добавил в /usr/portage/profiles/embedded/make.defaults:
ARCH="x86"
Но не уверен, возможно корректней указать: x86-winnt
Установка пошла. |

for armv7 ：
ln -s /usr/portage/profile/arch/arm/armv7 /usr/arm-cortex-a8*/etc/make.profile .
试试看。like this

apparently for mingw32 replacing the make.profile symlink by :
ln -s /usr/portage/profiles/arch/x86 make.profile
in /usr/i686-pc-mingw32/etc/portage
fixed the problem for me...
EDIT : no it didn't, the compilations work, but in the end the link report undefined reference to winmain16, so I guess I broke the libs I rebuilt... !!!
I guess I'll fall back to good old manual compilation without emerge then... ! |

Solved the same problem by editing
/usr/portage/profiles/embedded/make.defaults
and adding ARCH="x86"
(Crossdev for Mingw32) |

Modifying the /usr/portage/profiles/embedded/make.defaults file seems the incorrect approach.
I don't know enough about the emerge internals, but has anyone considered having a MinGW make.default?
Is it possible to create a mingw-based profile?
How can one tell crossdev and {x86_64-w64 | i686-pc}-mingw32 to use this profile? |

I bumbled across this thread while I was facing the same problem. Under the portage manpage, I finally noticed
| Code: |
make.defaults
...
PROFILE_ONLY_VARIABLES = ARCH
Prevent critical variables from being changed by the user in make.conf or the env.
...
|
So ARCH cannot be set under make.conf by design! Myself, I'm kinda annoyed that this broken thing was autogenerated for me.
The solution is to copy the profile's make.defaults to the profile override directory (typically /etc/portage/profile/, but I'm using crossdev so mine is /usr/armv7a-hardfloat-linux-gnueabihf/etc/portage/profile/). Now edit the overriding make.defaults to set ARCH. |

I found a potentially simpler solution, by just removing "ARCH" from PROFILE_ONLY_VARIABLES in the /usr/xxxx/etc/portage/make.profile/make.defaults. I say potentially because I'm not sure if this a good strategy.
