我使用 linux, 但對它很不熟..且也不太會用 fortran 若有語焉不詳之處請多包涵 我多年前有用一個 codes 計算工作需要的東西 那是用 fortran 寫的 當時都可以用 不過最近在 ./configure 之後卻無法 make 了（出現錯誤訊息） 不知道是不是更新了什麼 然後又缺了什麼東西 以下是 make 之後出現的錯誤訊息： gfortran -O2 -I. -o cmb cmbflat.o cmbopen.o driver.o lensing.o subroutines.o params.o recfast.o dverk.o cmbflat.o: In function `powersflat_': cmbflat.F:(.text+0x4b6): undefined reference to `_gfortran_pow_r8_i4' cmbflat.o: In function `finithermo_': cmbflat.F:(.text+0x1928): undefined reference to `_gfortran_pow_r8_i4' cmbflat.F:(.text+0x1d32): undefined reference to `_gfortran_pow_r8_i4' cmbflat.F:(.text+0x2c45): undefined reference to `_gfortran_pow_r8_i4' cmbflat.F:(.text+0x2dc4): undefined reference to `_gfortran_pow_r8_i4' cmbflat.o:cmbflat.F:(.text+0x6bcb): more undefined references to `_gfortran_pow_r8_i4' follow driver.o: In function `MAIN__': driver.F:(.text+0x2f): undefined reference to `_gfortran_set_std' driver.F:(.text+0x473): undefined reference to `_gfortran_pow_r8_i4' driver.F:(.text+0x495): undefined reference to `_gfortran_pow_r8_i4' lensing.o: In function `splint_v2_': lensing.f:(.text+0x12f): undefined reference to `_gfortran_pow_r8_i4' lensing.f:(.text+0x150): undefined reference to `_gfortran_pow_r8_i4' lensing.o: In function `cllens_': lensing.f:(.text+0x10e2): undefined reference to `_gfortran_pow_r8_i4' lensing.o:lensing.f:(.text+0x1116): more undefined references to `_gfortran_pow_r8_i4' follow collect2: ld returned 1 exit status make: *** [cmb] Error 1 有人可以解答嗎？感謝！ --
