# Helper class to handle creation of lv2 turtle files
|
|
|
|
# Turtle files (*.ttl) are created during compile usually. This does not work
|
|
# for us because cross build libraries cannot be opened by build host. To get
|
|
# around we:
|
|
#
|
|
# 1. Adjust build (see do_ttl_sed) so that instead calling LV2_TTL_GENERATOR
|
|
# the plugin file name is written to LV2_PLUGIN_INFO_FILE
|
|
# 2. Try to generate ttl with the help of qemu. This can faile for various
|
|
# reasons: SIMD instructions not supported / qemu itself / ...
|
|
# For files not handled properly we try:
|
|
# 3. Generate ttl-files at first boot / after package was installed
|
|
|
|
|
|
# File containing names of plugins to handle in do_compile_append
|
|
# Line-format expected: <some-path-in-build>/<plugin>.so
