+### reportlab
+
+When installing reportlab, you may encounter a compile error such as:
+
+```c
+    src/rl_addons/renderPM/libart_lgpl/art_pixbuf.h:38:41: error: expected ';', ',' or ')' before '.' token
+    typedef void (*ArtDestroyNotify) (void *func_data, void *data);
+                                            ^
+```
+
+This is due to a conflict in the reportlab source code and the AIX header files. As a workaround, you can define `_LINUX_SOURCE_COMPAT` to prevent the conflicting definition:
+
+```bash
+ CFLAGS=-D_LINUX_SOURCE_COMPAT pip3.9 install reportlab
+```
