Bug, duplicate symbols

[Wah0airo]

I tried to include ofxPD in a Project but I became a linker error, 30 duplicate symbols. I tried to compile the examples, but was the same, again 30 duplicate symbols. I found some similar posts, but I couldn't find any solutions. I looks like there is a problem with "g_list_all.h" . I follow the instructions from Readme file. The errors are lister below. I'm working with OF 0.98 on OSX Sierra, Xcode 8.3, ofxPd was compiled with the following flags: -DHAVE_UNISTD_H -DUSEAPI_DUMMY -DPD -DLIBPD_EXTRA -DLIBPD_USE_STD_MUTEX -DHAVE_LIBDL duplicate symbol glistreloadingabstraction in: g_all_guis.o g_array.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_bang.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_canvas.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_clone.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_editor.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_graph.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_guiconnect.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_hdial.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_hslider.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_io.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_mycanvas.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_numbox.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_readwrite.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_rtext.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_scalar.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_template.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_text.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_toggle.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_traversal.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_vdial.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_vslider.o duplicate symbol glistreloadingabstraction in: g_all_guis.o g_vumeter.o duplicate symbol glistreloadingabstraction in: g_all_guis.o m_binbuf.o duplicate symbol glistreloadingabstraction in: g_all_guis.o m_pd.o duplicate symbol glistreloadingabstraction in: g_all_guis.o s_inter.o duplicate symbol glistreloadingabstraction in: g_all_guis.o s_loader.o duplicate symbol glistreloadingabstraction in: g_all_guis.o x_array.o duplicate symbol glistreloadingabstraction in: g_all_guis.o x_misc.o duplicate symbol glistreloadingabstraction in: g_all_guis.o x_scalar.o duplicate symbol glistreloadingabstraction in: g_all_guis.o x_text.o ld: 30 duplicate symbols for architecture x86_64

Did you use the ProjectGenerator?

EDIT: I'm not seeing any issues in building the pdExample project with an Xcode project generated by the PG.

[Wah0airo]

Yes, I used the Project Generator. I create a new example too with the PG only with an example of ofxPD,, the "duplicate symbols" still appears. The rest of Open Frameworks addons are working OK.

I'm not seeing this issue with a fresh clone of ofxPd into a fresh download of OF 0.9.8. Both pdExample and an empty project using ofxPd build fine. I'm running macOS 10.12.4 and using Xcode 8.3.1.

I found the problem. When you create a new Xcode project you are asked to do "Update to recommended settings".Attached is a Screenshot. If do that, than is going to appear these duplicate symbols, if not the code compile without problems. Maybe this point "Duplicate methods definition" is generating this problem. If you look at the OF Forum you can see that another People had similar problems.

[danomatika]

Ok cool. In general, it's best not to update the project the PG generates.

As a followup, can you set the following in an updated project to see if it builds?

• Click on the project in the right-hand project tree
• Select the debug build target in the TARGETS list
• Click on the "Build Settings" tab
• Search for "No Common Blocks"
• Change the setting from "Yes" to "No"

[Wah0airo]

I changed the setting from "No common Blocks" in an updated project from "Yes" to "No", it builds. Regards.

"No common blocks" is now set via the "-fcommon" compiler flag in addon_config.mk.
