Building terragear

[swamp]

Correction. SHM was right but there were more problems with dependencies in Mint. I got tired of them not updating libraries in repos so I moved to Ubuntu 16.04. No problems installing CDAL 2.0 no telling the packages are broken etc. I think the cmake issue now is just a matter of me to typing in the right command. I will be on mumble in about 10 minutes.

Then that's good :S

the answer of your compiler comes to a surprise to me so far.
but try this

change

Code: Select all

cmake [parameters...]


for

Code: Select all

/usr/bin/cmake [parameters..]


And see if the response is the same

You are talking to an ignorant one today. What [parameters] ?

[SHM]

-D CMAKE_BUILD_TYPE="Release" -D CMAKE_CXX_FLAGS_RELEASE="-O3 -pipe" -D CMAKE_C_FLAGS_RELEASE="-O3 -pipe" -D CMAKE_INSTALL_PREFIX:PATH=/usr/share ../terragear

See I do have cmake.

that's great

I dont use gui, but something I am about to add confusion to you is, I recommend
1. Build the release/ws2.0 from the git
2. Build outside the source
3. choose any library path on the cmake command below that suits your OS installation (ie it is on LD_LIBRARY_PATH or you intend to add it)

http://www.thejabberwocky.net/viewtopic ... t=50#p7972

Code: Select all

Disclaimer. All commands below are safe, except last one. It is not inherently unsafe, but you are changing your terragear binaries anyway. In linux, everything you ran "sudo" or need to, it means you are applying somehow some sort of brute force.
I think this is what you inted, so go at it :D


Just do as follow

download terragear from sourceforce:
[anywhere in your drive, but I suggest you use /home/shm/sources]

Code: Select all

git clone git://git.code.sf.net/p/flightgear/terragear terragear


then enter terragear, you will need to change to the proper operative branch (master is /was broken) and anyways what you build with master no longer patches well scenery 2.0

Code: Select all

cd terragear
git checkout -t origin scenery/ws2.0


Then do the editions indicated in your post within that source you got there. (so you will compile your changes)

now. create and switch to a building directory outside the sources.

Code: Select all

mkdir ../terragear.builld
cd ../terragear.build


Building outside the sources is the safest way, and allows you to just remove the build directory and have a go at it again, if needed.

Then run this long command to configure the compilation. The Prefix indicated here is the same prefix I used to install terragear in your system, so keep it, or you end up with 2 terragears, and make it difficult for you to execute one or the other

Code: Select all

cmake -D CMAKE_BUILD_TYPE="Release" -D CMAKE_CXX_FLAGS_RELEASE="-O3 -pipe" -D CMAKE_C_FLAGS_RELEASE="-O3 -pipe" -D CMAKE_INSTALL_PREFIX:PATH=/usr/share ../terragear


All above is on single line!

after that thing finishes, run

Code: Select all

make -j 4


and finally when that finishes, run

Code: Select all

sudo make install


And then you had patched your terragear binaries.

That looks quite interesting actually. I never used the gui for cmake. A few notes




1. the source code NEEDS to be the correct branch of the git repository, it is scenery/ws2.0. Currently branch master did not compiled for me succesful, and last time it did, it had big problems with scenery being created right, and/or compatibility issues with ws2.0 (terrasync scenery). Apparently psadro has reworked much of the engine, partly attempting at a more stable state in terms of patching. So, really, make sure you are building the correct terrasync, which again is in the git repo, but It is NOT the master branch

2. Where to build. Do not make it the same place as the sources. Build on another directory. I use ../terragear.build but it is up to you.

3.Can you change the first parameter line that says CMAKE_BUILD_TYPE value cxx, for CMAKE_BUILD_TYPE value "Release". I don't think there is such cxx build type, and thus I am starting to believe this is the source of your problem

Good luck
