Hallo,

As a I am new to this list, FreePascal and Lazarus I need a little help by you to crosscompile our project to win32. Compiling to win64 however succeeds:

$ lazbuild --pcp=../../lazconf --os=win64 --cpu=x86_64 Tomboy_NG.lpi ...
Free Pascal Compiler version 3.1.1 [2017/11/27] for x86_64 Copyright (c) 1993-2017 by Florian Klaempfl and others (1002) Target OS: Win64 for x64

As you see, I installed FPC from trunk with the steps documented here: https://github.com/traumschule/tomboy/issues/2

I had to use the repository as the zip version
ftp.freepascal.org/pub/fpc/snapshot/trunk/source/fpc.zip (3.1.1) did not create ppcross386 for OS_TARGET=win32". With the version from trunk it works however.

Now compiling our project for i386 compared to above output another fpc is used and fails:

I assume the solution is to specify another compiler in ../../lazconf/environmentoptions.xml so I attached it. I am using Lazarus 1.8.0RC5 installed via deb from sourceforge. Without other advise I will try again with Lazarus from trunk.

If you want to try my steps, this repository may be of help: https://github.com/tomboy-notes/tomboy-ng

To build it, I use ansible for automation:
https://github.com/traumschule/tomboy

To explain the funny path above, these are the steps I did: cd ~/src
git clone https://github.com/traumschule/tomboy
cd tomboy
./bin/configure.sh # this installs lazarus, patches KControls and checks out tomboy-ng cd src/tomboy-ng
lazbuild --pcp=../../lazconf --os=win32 --cpu=i386 Tomboy_NG.lpi

Thanks!
kardan

Check your -Fu paths in /etc/fpc.cfg. They should contain the paths to fpc's i386-win32 ppu files.

Mattias

Really appreciate the fast reply!

This is what i found related to -Fu in /etc/fpc.cfg:

# searchpath for units and other system dependent things -Fu/usr/lib/fpc/$fpcversion/units/$fpctarget
-Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/*

#ENDIF

# searchpath for fppkg user-specific packages
-Fu~/.fppkg/lib/fpc/$fpcversion/units/$FPCTARGET/*

~/.fpkg does not exist, but there is another version in /etc:

$ ls /etc/fpc*
/etc/fpc-3.0.0.cfg  /etc/fpc.bak  /etc/fpc.cfg  /etc/fpc.cfg.bak

$ diff /etc/fpc.cfg /etc/fpc-3.0.0.cfg

From that I can't see why 3.0.4rc1 is used for win32. Kardan

You may have a different fpc.cfg (named .fpc.cfg << spot the dot on Linux) in your home folder.

Maybe ppc386 is in the PATH.

You can specify the compiler that lazbuild uses with --compiler=

Mattias

Hi,

summary: my fpc and ppcross* have different versions, because I can't build fpc with the installed version. Why does this happen:

~/src/fpc(master)$ make all
Makefile:2918: *** The only supported starting compiler version is 3.0.2. You are trying to build with 3.0.4.. Stop.

You may have a different fpc.cfg (named .fpc.cfg << spot the dot on Linux) in your home folder.

$ find /|grep 'fpc*.cfg'
/etc/fpc.cfg
/etc/fpc.cfg.bak
/usr/lib/fpc/3.0.4/ide/text/fp.cfg
/usr/share/fpcsrc/3.0.4/utils/fpcmkcfg/fpccfg.inc
/home/tomboy/src/fpc/utils/fpcmkcfg/fpccfg.inc

$ /home/tomboy/src/fpc# ls -ls /usr/share/fpcsrc/
total 4
4 drwxr-xr-x 9 root root 4096 Nov 21 16:25 3.0.4

(These version numbers are nonsense, just needed a way to separate the version from zip (3.1.1) and trunk (3.1.2) before I dropped the first.)

And where are your fpc's i386-win32 ppu files?

/usr/lib/fpc/3.1.1/units/i386-win32

$ find /usr/lib/fpc/3.1.1/units/i386-win32 -name '*.ppu'|grep system /usr/lib/fpc/3.1.1/units/i386-win32/winunits-base/mmsystem.ppu /usr/lib/fpc/3.1.1/units/i386-win32/rtl/system.ppu

> # searchpath for units and other system dependent things > -Fu/usr/lib/fpc/$fpcversion/units/$fpctarget > -Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/* > -Fu/usr/lib/fpc/$fpcversion/units/$fpctarget/rtl

So it should be found, no?

The term ppu was new to me. I just return from reading [1] and installed the binutils:
$ sudo apt-get install binutils-mingw-w64 binutils-powerpc-linux-gnu binutils-powerpc64-linux-gnu

true.

You can specify the compiler that lazbuild uses with --compiler=

--compiler=<ppcXXX>
override the default compiler. e.g. ppc386, ppcx64, ppcppc etc.

Now it's time to learn from you again.

Hi,

it looks like I need to train my patience a bit more.

can I still expect an answer or what did I do wrong?

Thanks for your hints!
Kardan

In general you need the last release of FPC to build the new FPC. And with release I don't mean release candidates. So 3.0.2 was the last release.
FPC 3.0.4 was released today, so FPC trunk will soon require 3.0.4.

Mattias

First rebuild your normal (not the cross version) FPC from trunk.

Then change your path environment variable to contain the new compiler's path. You can change it if you open the file .profile in your home folder. Add a new line to the end of the file. An example: export PATH=/home/the-new-path-comes-here/:$PATH
Logout and Login again to apply the changes.
You can check which compiler will be used with the 'which fpc" command.

Now you can build your cross compiler with your new compiler on the new path. The old one will be bypassed if everything is okay.

I hope I didn't miss anything...

What did I do wrong? Note that for me basic steps related to fpc are unknown, however I am able to follow the orders by the compiler output.

Thanks!
kardan

as noted previously, you /MUST/ use 3.0.2 to build 3.0.4... after 3.0.4 is adopted and made the minimum version, then you can use it to build newer versions greater than 3.0.4 but to build 3.0.4 you will /always/ have to use 3.0.2, the last release before 3.0.4 became available...

The hint about 'run fpcmake' is misleading here. Do not run it. Please revert any changes.
svn revert -R .

What did I do wrong? Note that for me basic steps related to fpc are unknown, however I am able to follow the orders by the compiler output.

It works here with the svn checkout of fpc trunk.
Maybe you fetched the wrong repository or you have local modifications or you have a different 'make'.
