Hallo! I have a suggestion for the tutorial page here: http://trac.seqan.de/wiki/BuildManual/IntegrationWithYourOwnBuildSystem These flags are recommended: Linux/GCC flags: -lrt (required) -W -Wall -Wno-long-long -pedantic -Wno-variadic-macros (optional). However, you should put somewhere that for some seqan functions you also need the -lz flag (I noticed this with the Record reader, although I am not entirely sure why this is needed to read one uncompressed FASTA file). -thanks & greetings! -Peter Nick.
