Hello,
as you seen here (https://issues.apache.org/jira/browse/THRIFT-177), I
am trying to cross-compile Thrift for the OpenWRT platform.
After a two-night-fight, my result are the following:
- I've created a OpenWRT package for thrift (see the attachment if you
are interested).
- I've successfully compiled the cpp-library (which results in
libthrift, libthriftz and libthriftnb)
- For now, I will not cross-compile the thrift-compiler since I will
compile the thrift definition files on my PC.
Coming to this point, I was very happy and I thought that the story
ends, but now I am faced with a problem I cannot solve myself:
For testing my cross-compilation result, I cross-compiled the cpp-part
of the thrift tutorial. I installed the cross-compiled libraries on the
target device and start the CppServer and the only reaction was
"Segmentation Fault" :-(
I tried to backtrack the problem and I came to the finding, that a
simple hello world program, which is linked to my cross-compiled
thrift-library, causes the "Segmentation Fault". Without linking the
thrift-library, everything is O.K.
=======================
------------
Hello.cpp
------------
#include <iostream>
using namespace std;
int main(int argc, char **argv) {
printf("Hello World!\n");
return 0;
}
1) First try
$ i386-linux-uclibc-g++ -L${LIB_DIR} -levent -lthrift -o Hello Hello.cpp
On the target device:
root@OpenWrt:~# ./Hello
Segmentation fault
2) Second try
$ i386-linux-uclibc-g++ -L${LIB_DIR} -levent -o Hello Hello.cpp
On the target device:
root@OpenWrt:~# ./Hello
Hello World!
======================
I will try to debug it with gdb, but I'm not an expert in this.
So, please, can someone help me?
Kind regards,
Siamak Haschemi

define Package/libthrift/Default/description
Thrift is a software framework for scalable cross-language services
development. It combines a software stack with a code generation
engine to build services that work efficiently and seamlessly between
C++, Java, Python, PHP, Ruby, Erlang, Perl, Haskell, C#, Cocoa,
Smalltalk, and OCaml.
