Problem using discount library

[Abdeljalil]

i’m working on project that uses discount library.
http://www.pell.portland.or.us/~orc/Code/discount/
i installed the library on my machine and included:

#include <mkdio.h>

#include <mkdio.h>

To copy to clipboard, switch view to plain text mode 

and i have this piece of code:

MMIOT* document = 0;
    char* result;
    QString sourceMarkdown(markdown);
    if (!sourceMarkdown.endsWith('\n'))
        sourceMarkdown.append('\n');
    QByteArray data = sourceMarkdown.toUtf8();
    document = mkd_string(data,data.length(),MKD_NOPANTS);
    mkd_compile(document,MKD_NOPANTS);
    mkd_document(document,&result);
    QString renderedHtml = QString::fromUtf8(result);
    return renderedHtml;

MMIOT* document = 0;
    char* result;
    QString sourceMarkdown(markdown);
    if (!sourceMarkdown.endsWith('\n'))
        sourceMarkdown.append('\n');
    QByteArray data = sourceMarkdown.toUtf8();
    document = mkd_string(data,data.length(),MKD_NOPANTS);
    mkd_compile(document,MKD_NOPANTS);
    mkd_document(document,&result);
    QString renderedHtml = QString::fromUtf8(result);
    return renderedHtml;

usualy i use “-lmarkdown” flag to compile it (for discount shared library). but in Qt i dont know how.
i tried

QMAKE_LFLAGS += -lmarkdown

QMAKE_LFLAGS += -lmarkdown

To copy to clipboard, switch view to plain text mode 

and

unix|win32: LIBS += -lmarkdown

unix|win32: LIBS += -lmarkdown

To copy to clipboard, switch view to plain text mode 

but didn’t work.
any help?

The LIBS variant is the right one, but this will only find the library if it is in the compiler/linker's search path.
Usually the LIBS string also needs and -L directive to add the library's path to that.

welcom,
i tried this

LIBS += -L/usr/local/lib/ -lmarkdown

but didn't work either :-(
and the result is : undefined reference to ...

[ChrisW67]

Is /usr/local/lib where you installed the library?
Did you rerun qmake after making that change?
Is the "undefined reference to ..." Error message even related to the discount library? ... We cannot see.

[Abdeljalil]

the path is:
/usr/local/lib/libmarkdown.a
i'm using QtCreator and qmake should update automaticlly
sure :-) , undefined reference to mkd_string() mkd_compile() mkd_document()

[anda_skoa]

Does the library contain the symbol?

objdump -t /usr/local/lib/libmarkdown.a | grep  mkd_compile

objdump -t /usr/local/lib/libmarkdown.a | grep  mkd_compile

Thank you guys
i solved it, just used:

extern "C" {
#include <mkdio.h>
}

extern "C" {
#include <mkdio.h>
}
