Unable to compile with SkParagraph in c++ (Linux)

[M S]

Hi,

I'm trying to compile a small test program in which i attempt to draw text using SkParagraph but while compiling im getting following error

>> g++ -o nn  main.cpp -lskia -lskshaper -ldl -lharfbuzz -lharfbuzz-subset -lpthread -ljpeg -lfreetype -licu -lz -lpng -lfontconfig -lwebp -lwebpmux -lwebpdemux -lskparagraph -lpathkit -lskunicode_core -lskcms -lwuffs -lzlib -lexpat -lskunicode_icu -lGL -I. -Ithird_party/skia -Lthird_party/skia/out/Static

==========================================

what am i missing is it some dependency and btw im not been able to compile skia without any warning of AVX.

Any help appreciated!

Your library linking order is wrong - for example, the last error - libskparagraph.a looks for SkShapers::HB::PurgeCaches(), which is in libskshaper, but you have -lskshaper near the front. It should be behind -lskparagraph . You need to re-order the library linking order so that the dependent ones are in the later. Another example, -lskia should be somewhat towards the end, since most of the others depend on it!
