## Installation:
create a devenv isolated package environment

devenv add sci
devenv use sci

xcb dependencies

# # required from some xcb libs
devenv build automake
export ACLOCAL_PATH="$(aclocal --print-ac-dir)"

devenv build pkgconfig
alias pkg-config="$(which pkg-config)"
export PKG_CONFIG_PATH="$(pkg-config --variable pc_path pkg-config):/usr/lib64/pkgconfig:/usr/share/pkgconfig:${DEVENVPREFIX}/lib64/pkgconfig"

devenv build xcb

python

devenv build cmake

devenv build openssl
alias openssl="$(which openssl)"
# # openssl version still shows old version number, but it is okay
# # ref: https://serverfault.com/a/789992

make buildext viewer VERBOSE=1 

## (debug) 如果安裝中途Terminal斷線/被關掉
載入已經安裝過的套件的環境變數, 並從中斷的地方繼續

devenv use sci

export ACLOCAL_PATH="$(aclocal --print-ac-dir)"
alias pkg-config="$(which pkg-config)"
export PKG_CONFIG_PATH="$(pkg-config --variable pc_path pkg-config):/usr/lib64/pkgconfig:/usr/share/pkgconfig:${DEVENVPREFIX}/lib64/pkgconfig"
alias openssl="$(which openssl)"

## Testing modmesh
使用GUI Node測試

> Taiwania-1 User Guide: https://iservice.nchc.org.tw/nchc_service/nchc_service_qa.php?target=20

打開一個Terminal

devenv use sci

cd ~/modmesh/build/dev310/cpp/binary/viewer

./viewer

result

# rebuild modmesh

make cmakeclean
make buildext viewer VERBOSE=1
