I build it to run tessearctmain.cpp.
I do not intend to compile the whole
Thanks to instruction from Zdenko, I add the symbols as follows:
In Eclipse, Project Properties->C/C++ General->Paths and Symbols
Symbol, Value.
USE_STD_NAMESPACE
VERSION=\"3.02.02\"
Now building succeeds.
Compile has errors, complaining there are several main() functions.
I have little knowledge of makefile, which I guess can circumvent this
problem, so I renamed all functions with main(), except tesseractmain.cpp,
to .txt files.
Now the compiling errors are:
svutil.cpp:129: undefined reference to `sem_init'
svutil.cpp:137: undefined reference to `sem_post'
svutil.cpp:145: undefined reference to `sem_wait'
svutil.cpp:188: undefined reference to `pthread_create'
I search the word “sem_init”, which is in the configure file.
I do not understand the configure file.
Finding some commands containing “sem_init”
{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for library containing
sem_init" >&5
char sem_init ();
int
main ()
{
return sem_init ();
;
return 0;
}
Google, found http://code.google.com/p/tesseract-ocr/issues/detail?id=757
“The build fails as sem_init is in librt on Solaris. The attached patch
adds searching for sem_init in librt. After that the build succeeds.”
Search librt in the libraries:
/usr/lib/x86_64-linux-gnu/
librt.a
librt.so
So I include /usr/lib/x86_64-linux-gnu into the Library Paths
Include rt into Libraries.
Rebuild the project with hope....
Again, the same compiling errors are:
svutil.cpp:129: undefined reference to `sem_init'
svutil.cpp:137: undefined reference to `sem_post'
svutil.cpp:145: undefined reference to `sem_wait'
svutil.cpp:188: undefined reference to `pthread_create'
I guess I need to include some header files. But I failed to find one.
Or do I have to learn autotool to achieve what I want?
An easy way?
