同樣的命令用V1.91帶的GCC8.2.0編譯正常

請(qǐng)問(wèn)這可能是什么問(wèn)題?

下了個(gè)?MounRiver_Studio_Community_Linux_x64_V170.tar.xz, 換成這里面自帶的 GCC 12 編譯就沒(méi)問(wèn)題. 粗略對(duì)比了一下兩個(gè)目錄, 文件大小都是一樣的, 但是MRS自帶的就正常, 換成V1.91里的就會(huì)報(bào)錯(cuò), 這是什么情況??

您好，我這邊V19.1工具鏈沒(méi)有復(fù)現(xiàn)您的現(xiàn)象，cc1找不到可能和目錄更改或者部分環(huán)境變量類(lèi)似GCC_EXEC_PREFIX設(shè)置導(dǎo)致的，您可以自查一下，如還有問(wèn)題，可聯(lián)系郵箱yangy@wch.cn進(jìn)一步溝通
