makefile $(()) in another () cause right parentheses ambiguous

In my makefile, I want to output a file with size command output format using the contents of readelf command outputs.



I can successfully execute the commands in shell script, but when I put the commands in makefile, $((16#$${hex})) doesn't work so dec doesn't have values. I guess from the vim UI text color that it may be the last ) of $((16#$${hex})) doesn't match correctly. I'm not quite familiar with makefile, anyone knows how to deal with this?



size.txt : Makefile

    $(MAKE) objs

    echo " text    data     bss     dec     hex filename ">$@

    (for X in `find . -name '*.o' -print` ; do 

        hex=`readelf -S -W $$X | grep 'sAXs' | sed 's/ss*/ /g' | cut -d ' ' -f 8`; 

        dec=`echo $((16#$${hex}))`;

        echo " $${dec}   0    0    $${dec}    $${hex} $$X"; 

    done) >>$@


Now the output is 0 0 00000030 xxxx.o and the expected output is 48 0 0 48 00000030 xxxx.o.

    echo $((16#$${hex})) -> echo $$((16#$${hex})). You forgot to escape the make-expansion.

Monofisismo

Image
Monofisismo (do grego: monos - "único, singular" e physis - "natureza") é o ponto de vista cristológico que defende que, depois da união do divino e do humano na encarnação histórica, Jesus Cristo, como encarnação do Filho ou Verbo ( Logos ) de Deus, teria apenas uma única "natureza", a divina, e não uma síntese de ambas. O monofisismo é contraposto pelo diofisismo (ou "diafisismo"), que defende que Jesus preservou em si as duas naturezas. Historicamente, o monofisismo se refere primordialmente à posição dos que (especialmente no Egito e, em menor grau, na Síria) rejeitaram as decisões do Concílio de Calcedônia em 451 (o quarto concílio ecumênico). Os membros mais moderados entre eles, porém, defendem a teologia "miafisita", que se tornou a oficial para as Igrejas Ortodoxas Orientais. Muitos ortodoxos orientais, porém, rejeitam essa classificação, mesmo como um termo genérico, mas ele é amplamente utilizado na literatura históri...

Angular Downloading a file using contenturl with Basic Authentication

0 I have a contentUrl when user clicks on that,file should be downloaded. If I try to browse the contentUrl in the browser it asks for Userid and password.I believe this is Basic Authentication.I dont want user to enter UserId and Password so I am passing it Authorization(Please see below code).

Olmecas

Image
Monumento 1, uma das quatro cabeças colossais encontradas em La Venta, com altura aproximada de 3 metros Olmecas é a designação do povo e da civilização que estiveram na origem da antiga cultura pré-colombiana da Mesoamérica e que se desenvolveram nas regiões tropicais do centro-sul do atual México durante o pré-clássico, próximo de onde hoje estão localizados os estados mexicanos de Veracruz e Tabasco, no Istmo de Tehuantepec, numa zona designada área nuclear olmeca. A cultura olmeca floresceu nesta região aproximadamente entre 1500 e 400 a.C., [ 1 ] e crê-se que tenha sido a civilização-mãe de todas as civilizações mesoamericanas que se desenvolveram posteriormente. [ 2 ] No entanto, desconhece-se a sua exacta filiação étnica, ainda que existam numerosas hipóteses colocadas para tentar resolver esta questão. O etnónimo olmeca foi cunhado pelos arqueólogos do século XX, e não devem confundir-se com os muito posteriores olmecas-xicalancas que ocuparam vários locais do México...
