Re: [PATCH v6 4/7] env: Allow U-Boot scripts to be placed in a .env file

Dear Simon,

In message CAPnjgZ3KS06_cy8mLL2V-ezqZYO6QEecz2C78hVaUQAnAz0fNg@mail.gmail.com you wrote:

I thought you were trying to use + at the end of a variable.

I used:

fred+=aaa

and got

cc1: warning: unknown escape sequence: '=''

You can try it yourself by editing sandbox.env in the u-boot-dm/env-working tree.

Hmmm...

-> cat foo.c #define A ampersand #define B berta

foo+=B; -> gcc -E foo.c # 0 "foo.c" # 0 "<built-in>" # 0 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 0 "<command-line>" 2 # 1 "foo.c"

foo+=berta;

-> cat bar.c fred+=aaa -> gcc -E bar.c # 0 "bar.c" # 0 "<built-in>" # 0 "<command-line>" # 1 "/usr/include/stdc-predef.h" 1 3 4 # 0 "<command-line>" 2 # 1 "bar.c" fred+=aaa

I do not see this problem...

Best regards,

Wolfgang Denk
