Re: [Seqan-dev] Using seqan in stock Xcode project

[Alexander Griekspoor <mekentosj@gmail.com>]

Hi Dave,

Good news, I managed to get things to compile with help of your
instructions, thank you so much!
For future reference here's what I did (pretty much as Dave suggested):

- create a stock Cocoa app in Xcode4 using File -> New Project  (using ARC)
- renamed AppDelegate.m to AppDelegate.mm, import seqan.h
- followed the steps Dave outlined to get all forwards:

cd seqan-trunk
mkdir build; cd build
cmake .. -G "Unix Makefiles"
make alignment

- did one extra make to get the the forwards for build/extras/include
that make alignment doesn't create:

make alf

- in the Xcode build settings added the following User header paths:

seqan-trunk/core/include
seqan-trunk/extras/include
seqan-trunk/build/core/include
seqan-trunk/build/extras/include

- and activate the Always Search User Paths option to YES

that's it.

I do get about 100 of these warnings:

/Users/mekentosj/molbio/seqan-trunk/core/include/seqan/random/random_mt19937.h:90:16:{90:16-90:33}{90:9-90:15}:
warning: implicit conversion loses integer precision: 'MTRand::uint32'
(aka 'unsigned long') to 'unsigned int' [-Wshorten-64-to-32,3]

not sure how we could avoid these?

Again, many thanks for the help, the library looks very promising and
we're seriously considering using it in one or more future products.
To be continued…
Alex
