    <p>I'm trying to call external C program. The same code already works on linux and windows, but not on solaris.<br> Can somebody take a look?<br> Original example is taken from <a href="http://csl.name/C-functions-from-Python/" rel="nofollow">http://csl.name/C-functions-from-Python/</a><br> C code (myModule.c)</p> <pre><code>#include &lt;Python.h&gt; static PyObject* py_myFunction(PyObject* self, PyObject* args) { char *s = "Hello from C!"; return Py_BuildValue("s", s); } static PyObject* py_myOtherFunction(PyObject* self, PyObject* args) { double x, y; PyArg_ParseTuple(args, "dd", &amp;x, &amp;y); return Py_BuildValue("d", x*y); } static PyMethodDef myModule_methods[] = { {"myFunction", py_myFunction, METH_VARARGS}, {"myOtherFunction", py_myOtherFunction, METH_VARARGS}, {NULL, NULL} }; void initmyModule() { (void) Py_InitModule("myModule", myModule_methods); } </code></pre> <p>Python calling it</p> <pre><code>from myModule import * print "Result from myFunction:", myFunction() print "Result from myOtherFunction(4.0, 5.0):", myOtherFunction(4.0, 5.0) </code></pre> <p>Compiling on Linux (tested on RHEL)</p> <pre><code>gcc -fPIC -shared -I/usr/include/python2.6 -lpython2.6 -o myModule.so myModule.c </code></pre> <p>Compiling on Windows XP under MinGW</p> <pre><code>gcc -Ic:/Python27/include -Lc:/Python27/libs myModule.c -lpython27 -shared -o myModule.pyd </code></pre> <p>But I can't get it to work on solaris. I can compile it with</p> <pre><code>gcc -fPIC -I/usr/include/python2.4 -L/usr/lib/python2.4 myModule.c -lpython2.4 -shared -o myModule.so </code></pre> <p>but it fails with an error</p> <pre><code>from myModule import * ImportError: ld.so.1: python2.4: fatal: libgcc_s.so.1: open failed: No such file or directory </code></pre> <p>Can someone help me figure it out? <pre> gcc is 3.4.6 Python is 2.4.6 solaris 10 on x86 machine </pre></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
