errors trying to compile a basic sample using XCode 4

[Jean-François khaelis]

Hello

i'm trying to build a simple hello world project using wxWidgets (tried
2.9.5 and 3.0.0)

i managed to build the source code (not easily but it finally worked) using
the XCode projects (i tried using Terminal but i had weird EXC_BAD_ACCESS
errors)

so here are the errors:
http://pastebin.com/WTY4tBcQ

thanks

This may be part of the problem. You seem to have wxWidgets headers
installed globally in the system and perhaps from a different version.

The errors here are "impossible" if you only have a single set of
wxWidgets headers (starting from the very first one). So please delete all
wxWidgets headers and libraries from your system (use find/spotlight to
ensure that there are no setup.h files left anywhere), then rebuild
wxWidgets 3.0.0 in the usual way and it should work just fine.

thanks

so I tried to start all over from the beginning with a clean OS X install.

This time i didn't build wxWidgets from Terminal but from the XCode
projects included with wxWidgets 3.

The two static or dynamic libraries build fine (just a few warnings) but
there is no ouput file anywhere (inside DerivedData, or even XCode.app
folder) There is no .a file nowhere. The previous .a files i had before
were from the Terminal build i guess

where do i go from there ?

Will i have more chance this time to build 3.0 using the Terminal without
getting the EXC_BAD_ACCESS error after?

thanks for help

XCode places its output elsewhere. e.g.
Users/Me/Library/Developer/Xcode/DerivedData but you can change this.
Google "xcode output directory"

okay found it. I tried a global search for .a files but it didn't show,
weird (i have system files unhidden)

i'm sorry i'm such a noob (i'm a good PC programmer and got wxWidgets
working on PC but Mac is such another world for a beginner)...

thanks a lot

And what happen if you try to build from the Terminal?
Did the configure pass? Did you use any special configure option?
What error message did you get if any?

Thank you.

BTW, the pastebin link is removed.

Can you build the minimal sample from wxWidgets distribution?

Can you just simply do this in Terminal:
cd <wxWidgets_build_dir>/samples/minimal
make

The wxWidgets distribution comes with the numbers of sample code.

Also what is your configure line?

Thank you.

there are a lot of makefiles in the minimal folder

1) i tried "make -f makefile.unx" but it tries to execute a bunch of
"wxconfig" that don't launch because i didn't install using Terminal

2) i tried to build minimal from XCode : I had to select an executable in
the scheme edition because nothing was happenning when i was compiling the
libraries.

But now everything works, the main window launches!!

now i have to figure why i have errors in the previous source. (maybe a
build setting?)

i'll do that and get back to you if you're interested.

thank you so much!

Jeff

[Jean-François khaelis]

i somehow ended up with just a few errors but i don't explain them. now i
got this : pastebin.com/jWSmU2qn
(most errors went away when i added the preprocessor flags but globally i
copied all the settings from minimal to my new project)

i know i could start over from minimal but i want to know what went wrong.

If you didn't build wxWidgets using configure+make you can't use this
makefile. OTOH if you do build it using configure+make, then you also get
the makefiles for all the samples under the build directory which you can
then build easily.

okay i finally got it working (pfieeuw)

Here is how to do :
1 - open "wxcocoa.xcodeproj" in "wxwidgets-3.0.0/build/osx" and compile

if build is succeeded file should be in:
"usr/library/Developer/XCode/DerivedData" (and nowhere else like i read
everywhere)

next create a new Cocoa project. Erase *everything* including folders

copy the target you want (static or dynamic) from "minimal_cocoa.xcodeproj"
(in wxwidgets-3.0.0/samples) and import it to the new project (this way you
got everything set to get it working)

copy files :
Info_cocoa.plist
*.xcconfig
from the "minimal_cocoa.xcodeproj" to your new project

don't forget to change the parameter "Info.plist file" in
"Packaging/Info.plist" file to match the file you copied
("Info_cocoa.plist")

next drag n drop the created static lib .a to "Link binaries with
Libraries" in "Build Phase"

and you're done, everything should work.


I don't understand why there is not ONE tutorial that is good enough to
explain this. They are all buggy/unacceptable (like building from terminal
installs a lot of shaïte everywhere what if you want to use multiple
versions of wxWidgets? i'ts a mess then)

so follow this and you should be good

Probably because nobody wrote it yet? It seems that most people seem to be
happy to make it work on their own system but don't bother to record their
experience to help the others. If, by chance, you'd like to change this,
please add (or edit) the corresponding page on wxWiki.

No, it isn't. Multiple versions of wxWidgets, i.e. those with different
version numbers, can coexist on the same system. If you use multiple builds
of the same version, then things are more complicated, but the simplest
solution is to simply not run "make install" then and use uninstalled
wx-config, this works perfectly well and there are no real advantages to
installing if you link statically anyhow.

okay this is beginning to become a* nightmare*

it WAS working, i saw it with my eyes wide open and since i rebooted i
doesn't work

the minimal sample is greatly working though

what i did is to copy *every* single option in the minimal project to my
project but no luck.

the error messages seems to hit about png lib or something :
pastebin.com/U2wFJ4pv

I don't get what's wrong. The two projects minimal and mine are almost
identical now as i removed the building subproject from minimal and linked
with the library
*so the problem doesn't come from the library*

but from where?

thanks for help

Jeff

[Jean-François khaelis]

also i made some mistake in my previous tuto, i forgot a lot of things to
do, but as soon as it works i'll do it neatly

[Jean-François khaelis]

i maybe have a lead:
in the building options, there is a flag OTHER_LDFLAGS = -framework Webkit
...etc which is located in the wxcocoa.xcconfig file

but when i try to insert $(OTHER_LDFLAGS) in a buidling option, nothing is
written : Xcode doesn't make the link between the flag set in
wxcocoa.xcconfig and the build setting (it's working in the minimal project)

i think i correctly set the wxconfig files in the Configuration set (i
copied what was in the minimal project) so i assigned the wxconfig files to
debug and release modes and to the project.


*why does xcode doesn't know the OTHER_LDFLAGS in the wxcocoa.xcconfig ?*
Jeff

[Jean-François khaelis]

oooh it's working!! i was aassigning the *project* to* wxcocoa* and the*
target* to *wxdebug* but it's the opposite, so now everything is working
yay!

[Jean-François khaelis]

Vadim

could you pinpoint me the right page on the wiki to update? i don't want to
waste so good page....
