usando o awk para pegar dados da localização dinâmica

Question

Eu compilei alguns códigos e tenho toneladas de erros, e quero criar uma tabela que mostrará algumas coisas: o caminho do arquivo de origem, o número da linha e a referência indefinida. O primeiro e o segundo não são muito problemáticos para escavar usando um simples awk e imprimir $ 1, $ 2 etc, mas a referência indefinida é problemática, já que aparece em diferentes lugares na saída.

Aqui, um trecho do log de erros que estou tentando analisar com um script que quero escrever.

external/protobuf/src/google/protobuf/arena.h:309: error: undefined reference to 'fishy_proto::Service::Service()'

Como você pode ver, as linhas 1 e 14 mostram a referência indefinida em lugar diferente das outras linhas.

Existe uma maneira de executar um awk que ignore a localização exata, mas ainda traga o valor para a referência indefinida?

    

Answer 1

Sua saída de amostra indica que a "referência indefinida" sempre será o campo final awk de uma linha. Em awk , NF será o número de campos e $NF será o campo cujo número é "o número de campos", ou seja. o campo final, que é o que você está pedindo.

awk '{print "undefined reference = " $NF}'

    

Answer 2

the path of the source file, line number, and the undefined reference to

sed solução:

sed -E 's/^([^:]+):([0-9]+): error: undefined reference to (.*)/  /' file

A saída:

Answer 3

Se você não se importa em usar o perl:

perl -pe 's/^(.*?):(\d+): error: undefined reference to (.*)/\t\t/g'

A saída do seu exemplo ficaria assim:

Eu fiz pelo método abaixo usando sed

sed -ne "s/\(.*error:\)\(.*reference to \)\('.*'\)//p" inputfile
