Hi,

I'm porting AppWeb to Coldfire but I have found some problems linking dynamic libraries.
I have followed the next steps to cross compile.

Code:
CFLAGS='-march=isac -mcpu=54455 -msoft-float'
AR=m68k-linux-gnu-ar
CC=m68k-linux-gnu-gcc
LD=m68k-linux-gnu-ld
CXX=m68k-linux-gnu-gcc
RANLIB=m68k-linux-gnu-ranlib
NM=m68k-linux-gnu-nm
STRIP=m68k-linux-gnu-strip
./configure --host=m68k-linux --disable-multi-thread --disable-samples --disable-doc --without-php --without-sql --disable-cgi

make TRACE=1


During cross-compiling phase, the " Fatal error: Tried to convert PC relative branch to absolute jum" raises:
Code:

Do you have any idea to solve this problem?

Do you have src/mpr/mprPcre.c?

It should be there in the source dist -- where did u get the source?

yes, this file exists in the path src/mpr. (I downloaded some months ago appweb 3.1.2 tar gz)
It seems that -DPIC and -fPIC are not supported with m68k-linux-gnu-gcc, do you know?
Change configure, disabling the shared option, cross compile works fine...but I need to have dynamic libraries.

Any further idea? Thanks
Simone

u may need to edit the compiler flags in build/make/config.gcc

then make clean ; make compile

I have removed these options and launched configure with --shared.
The error "Fatal error: Tried to convert PC relative branch to absolute jump" still remains.
So I decided to configure Appweb with --static option ...

When I build my application (I'm trying to include statically Appweb), I have the next errors

Then I disable multi-thread option and build phase works fine.
Is it the right way to include Appweb statically?
Thanks for your answer and patience

You will need to solve the compiler flags for the PIC issue. You won't be able to run until you sort those flags out. You'll just need to try various options and consult your tool chain specialists. Static vs Dynamic should not have an impact on this error.

Please update to the latest source from github.com/embedthis/appweb-3. I think there has been a fix for static building.

Hi,

I'm trying to cross-compile but I have several assembler errors. I have attached the log.
Could you please suggest me a way to solve it?
Thanks for your help
Simone
