POCO on the iPhone

[mvl]

When building for iOS with Xcode 4.3 and up, another change is needed to the build configuration file located at <poco>/build/config/iPhone. Since Xcode and the platform SDKs for iOS are now self-contained in the Xcode.app's bundle, rather than being in a /Developer directory, I changed the line in the config file from this:

Code: Select all

TOOL_PREFIX  ?= /Developer/Platforms/$(IPHONE_SDK).platform/Developer/usr/bin 

to this:

Code: Select all

TOOL_PREFIX ?= $(shell xcode-select --print-path)/Platforms/$(IPHONE_SDK).platform/Developer/usr/bin

This worked for me using Xcode 4.5.2. Not that I mind configure/make, but it would be nice to have an Xcode project which had targets for the various Apple platforms, and did the 'lipo' script to zip the architectures together for iPhone and iPhoneSimulator.

Thanks!

I'm trying to compile POCO on the iPhone and I'm getting an error to do with FPEnvironment.h. For some reason I'm getting an error that copysignf and copysign are not a part of std librar. If I compile for Darwin I don't have any trouble. Below is the terminal window stuff.

Please re-download the 1.4.6 sources. This has been fixed in a "last minute" change. Or get the corrected FPEnvironment_DUMMY.h file from GitHub: https://raw.github.com/pocoproject/poco ... nt_DUMMY.h

In trying to cross compile the library from Linux to Windows (with i586-mingw32msvc-...) and checking for the latest version of
FPEnvironment_DUMMY.h
something similar happens:

just remove the std:: in front of the offending lines and it'll be ok. That was requested by Android users and it created a mess because copysign are C99 but not really C++ standard yet (just TR1). Will be properly taken care of in future releases.

I'm trying to compile POCO on the iPhone and I'm getting an error to do with FPEnvironment.h. For some reason I'm getting an error that copysignf and copysign are not a part of std librar.

I am also getting this error on Windows 7 when using cygwin, GCC version 4.5.3. I am trying to build poco-1.5.1. I note that the code in 1.5.1 does not include the fix for apple and android but even if it did, more is needed for cygwin.

Hi,

I've managed to build POCO 1.4.6 on iPhone and trying to implemented it into my project. But I got a lot of error in cstring like

no member named "xxxxx" in global namespace

I'm using xcode 4.5.2 with MAC OS X 10.8.2.
Thank you in advance

I got a lot of error messages like:

"ls: /Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/llvm-gcc-*: No such file or directory"

Any idea? Thanks

Same error here.
