I noticed a thread on the Wattage forum that mentioned a new format for Ergomo CSV files. The poster also mentioned that they hadn’t used Golden Cheetah because they thought it was for Linux only. Anyway, I got a copy of an Ergomo CSV file and got to work on making GC.

It was pretty simple to update. Justin had already wrote the code to read in PowerTap csv files. I just wrote in the logic to determine which flavor of CSV was being read and to parse the data in the way GC expects.

Still need more testing. The only Ergomo CSV file I have has German headers (ZEIT,STRECKE…). Hopefully I’ll get other versions of the files to test.

Golden Cheetah is universal! (i hope)

I spent most of the evening setting up my development environment to get Golden Cheetah to compile as a universal OS X application. This would be made easier if I actually knew what I was doing. In the end, I recompiled Qt4.3.1 and QWT5.0.2 as universal before I could move forward with building GC.

Here’s the configure command for Qt (one line):

./configure -static -prefix /usr/local/Qt4.3u-static -make libs
-confirm-license -universal -sdk /Developer/SDKs/MacOSX10.4u.sdk
-qt-sql-sqlite -LD="gcc -mmacosx-version-min=10.4"

I’m using a non-standard install location for the static libraries so I can update Trolltech’s binaries separately. There was some problem with gcc under Leopard, so some special parameters needed to be passed along: -mmacosx-version-min=10.4

qmake’s .pro files needed to have some config variables set. Specifically, I had to add these lines to each of GC and QWT’s .pro files:

QMAKE_MAC_SDK=/Developer/SDKs/MacOSX10.4u.sdk
CONFIG+=x86 ppc

I was also getting linker visibility issues, which were resolved by additionally adding QMAKE_CXXFLAGS += -fvisibility=hidden to each of the .pro files as well. I don’t know if this is correct, but the resulting application seemed to work.

More testing is needed, but it’s finally working under 10.5 Intel and 10.4 PPC. Forcing the use of the 10.4 SDK and min version 10.4 did something right.

Enough tech…I need to ride.

Golden Cheetah is on the verge of a new release. Sean’s committed Justin and my changes for BikeScore and metric/english preference into the svn trunk. I’ve cleaned up some of the user interface and have compiled an OS X Intel version. More importantly, we now have a desktop icon for the application under OS X…it’s all about aesthetics, really.

We’re discussing the next round of planned features now…it’s exciting.

We sorted out the build issues largely, however I still haven’t been able to confirm if the problem was isolated to the target machine or to 10.4 in general. Regardless, the Dr. Phil Skiba’s BikeScore algorithm has been incorporated by Justin Knotzke using a bit of the code I had originally developed for Dr. Coggan’s Training Stress Score (TSS/NP) into unreleased dev builds of Golden Cheetah. Hopefully this will be rolled into the release branch soon.

This is an interesting metric. I’m going to begin to use it in ernest in my training and will compare it the the TSS I have been using.

after rebuilding GoldenCheetah every which way I could think of to get it to run on 10.4 Intel, the end solution for this specific case was to upgrade the target computer to 10.5. i’m not satisfied with this, but am too busy with other work to invest more time on it for now.

I’ve been struggling for the past couple of days trying to get GoldenCheetah to compile correctly on my MacBook. I had to setup the development environment again after my first MacBook was RMA’d with a busted top case. This time I’m building under Leopard and can’t seem to be able to get Qtopia to make a 10.4 compatible binary. ugh. I’ve set the appropriate qmake flags, but it is still crashing on the 10.4.11 target system. I’ll keep looking until it works or I find that I’m attempting the impossible. I think it’s just my own ignorance in the end.
